-# block-stream
-
-A stream of blocks.
-
-Write data into it, and it'll output data in buffer blocks the size you
-specify, padding with zeroes if necessary.
-
-```javascript
-var block = new BlockStream(512)
-fs.createReadStream("some-file").pipe(block)
-block.pipe(fs.createWriteStream("block-file"))
-```
-
-When `.end()` or `.flush()` is called, it'll pad the block with zeroes.

+# env-paths [![Build Status](https://travis-ci.org/sindresorhus/env-paths.svg?branch=master)](https://travis-ci.org/sindresorhus/env-paths)
+
+> Get paths for storing things like data, config, cache, etc
+
+
+## Install
+
+```
+$ npm install --save env-paths
+```
+
+
+## Usage
+
+```js
+const envPaths = require('env-paths');
+const paths = envPaths('MyApp');
+
+paths.data;
+//=> '/home/sindresorhus/.local/share/MyApp-nodejs'
+
+paths.config
+//=> '/home/sindresorhus/.config/MyApp-nodejs'
+```
+
+
+## API
+
+### paths = envPaths(name, [options])
+
+#### name
+
+Type: `string`
+
+Name of your project. Used to generate the paths.
+
+#### options
+
+##### suffix
+
+Type: `string`<br>
+Default: `'nodejs'`
+
+**Don't use this option unless you really have to!**<br>
+Suffix appended to the project name to avoid name conflicts with native
+apps. Pass an empty string to disable it.
+
+### paths.data
+
+Directory for data files.
+
+### paths.config
+
+Directory for config files.
+
+### paths.cache
+
+Directory for non-essential data files.
+
+### paths.log
+
+Directory for log files.
+
+### paths.temp
+
+Directory for temporary files.

-Like FS streams, but with stat on them, and supporting directories and
-symbolic links, as well as normal files.  Also, you can use this to set
-the stats on a file, even if you don't change its contents, or to create
-a symlink, etc.
-
-So, for example, you can "write" a directory, and it'll call `mkdir`.  You
-can specify a uid and gid, and it'll call `chown`.  You can specify a
-`mtime` and `atime`, and it'll call `utimes`.  You can call it a symlink
-and provide a `linkpath` and it'll call `symlink`.
-
-Note that it won't automatically resolve symbolic links.  So, if you
-call `fstream.Reader('/some/symlink')` then you'll get an object
-that stats and then ends immediately (since it has no data).  To follow
-symbolic links, do this: `fstream.Reader({path:'/some/symlink', follow:
-true })`.
-
-There are various checks to make sure that the bytes emitted are the
-same as the intended size, if the size is set.
-
-## Examples
-
-```javascript
-fstream
-  .Writer({ path: "path/to/file"
-          , mode: 0755
-          , size: 6
-          })
-  .write("hello\n")
-  .end()
-```
-
-This will create the directories if they're missing, and then write
-`hello\n` into the file, chmod it to 0755, and assert that 6 bytes have
-been written when it's done.
-
-```javascript
-fstream
-  .Writer({ path: "path/to/file"
-          , mode: 0755
-          , size: 6
-          , flags: "a"
-          })
-  .write("hello\n")
-  .end()
-```
-
-You can pass flags in, if you want to append to a file.
-
-```javascript
-fstream
-  .Writer({ path: "path/to/symlink"
-          , linkpath: "./file"
-          , SymbolicLink: true
-          , mode: "0755" // octal strings supported
-          })
-  .end()
-```
-
-If isSymbolicLink is a function, it'll be called, and if it returns
-true, then it'll treat it as a symlink.  If it's not a function, then
-any truish value will make a symlink, or you can set `type:
-'SymbolicLink'`, which does the same thing.
-
-Note that the linkpath is relative to the symbolic link location, not
-the parent dir or cwd.
-
-```javascript
-fstream
-  .Reader("path/to/dir")
-  .pipe(fstream.Writer("path/to/other/dir"))
-```
-
-This will do like `cp -Rp path/to/dir path/to/other/dir`.  If the other
-dir exists and isn't a directory, then it'll emit an error.  It'll also
-set the uid, gid, mode, etc. to be identical.  In this way, it's more
-like `rsync -a` than simply a copy.

+node-gyp
+=========
+## Node.js native addon build tool
+
+`node-gyp` is a cross-platform command-line tool written in Node.js for compiling
+native addon modules for Node.js.  It bundles the [gyp](https://gyp.gsrc.io)
+project used by the Chromium team and takes away the pain of dealing with the
+various differences in build platforms. It is the replacement to the `node-waf`
+program which is removed for node `v0.8`. If you have a native addon for node that
+still has a `wscript` file, then you should definitely add a `binding.gyp` file
+to support the latest versions of node.
+
+Multiple target versions of node are supported (i.e. `0.8`, ..., `4`, `5`, `6`,
+etc.), regardless of what version of node is actually installed on your system
+(`node-gyp` downloads the necessary development files or headers for the target version).
+
+## Features
+
+ * Easy to use, consistent interface
+ * Same commands to build your module on every platform
+ * Supports multiple target versions of Node
+
+
+Installation
+------------
+
+You can install with `npm`:
+
+``` bash
+$ npm install -g node-gyp
+```
+
+You will also need to install:
+
+### On Unix
+
+   * `python` (`v2.7` recommended, `v3.x.x` is __*not*__ supported)
+   * `make`
+   * A proper C/C++ compiler toolchain, like [GCC](https://gcc.gnu.org)
+
+### On macOS
+
+   * `python` (`v2.7` recommended, `v3.x.x` is __*not*__ supported) (already installed on macOS)
+   * [Xcode](https://developer.apple.com/xcode/download/)
+     * You also need to install the `Command Line Tools` via Xcode. You can find this under the menu `Xcode -> Preferences -> Locations` (or by running `xcode-select --install` in your Terminal)
+       * This step will install `gcc` and the related toolchain containing `make`
+
+### On Windows
+
+#### Option 1
+
+Install all the required tools and configurations using Microsoft's [windows-build-tools](https://github.com/felixrieseberg/windows-build-tools) using `npm install --global --production windows-build-tools` from an elevated PowerShell or CMD.exe (run as Administrator).
+
+#### Option 2
+
+Install tools and configuration manually:
+   * Install Visual C++ Build Environment: [Visual Studio Build Tools](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools)
+   (using "Visual C++ build tools" workload) or [Visual Studio 2017 Community](https://visualstudio.microsoft.com/pl/thank-you-downloading-visual-studio/?sku=Community)
+   (using the "Desktop development with C++" workload)
+   * Install [Python 2.7](https://www.python.org/downloads/) (`v3.x.x` is not supported), and run `npm config set python python2.7` (or see below for further instructions on specifying the proper Python version and path.)
+   * Launch cmd, `npm config set msvs_version 2017`
+
+   If the above steps didn't work for you, please visit [Microsoft's Node.js Guidelines for Windows](https://github.com/Microsoft/nodejs-guidelines/blob/master/windows-environment.md#compiling-native-addon-modules) for additional tips.
+
+If you have multiple Python versions installed, you can identify which Python
+version `node-gyp` uses by setting the '--python' variable:
+
+``` bash
+$ node-gyp --python /path/to/python2.7
+```
+
+If `node-gyp` is called by way of `npm` *and* you have multiple versions of
+Python installed, then you can set `npm`'s 'python' config key to the appropriate
+value:
+
+``` bash
+$ npm config set python /path/to/executable/python2.7
+```
+
+How to Use
+----------
+
+To compile your native addon, first go to its root directory:
+
+``` bash
+$ cd my_node_addon
+```
+
+The next step is to generate the appropriate project build files for the current
+platform. Use `configure` for that:
+
+``` bash
+$ node-gyp configure
+```
+
+Auto-detection fails for Visual C++ Build Tools 2015, so `--msvs_version=2015`
+needs to be added (not needed when run by npm as configured above):
+``` bash
+$ node-gyp configure --msvs_version=2015
+```
+
+__Note__: The `configure` step looks for the `binding.gyp` file in the current
+directory to process. See below for instructions on creating the `binding.gyp` file.
+
+Now you will have either a `Makefile` (on Unix platforms) or a `vcxproj` file
+(on Windows) in the `build/` directory. Next invoke the `build` command:
+
+``` bash
+$ node-gyp build
+```
+
+Now you have your compiled `.node` bindings file! The compiled bindings end up
+in `build/Debug/` or `build/Release/`, depending on the build mode. At this point
+you can require the `.node` file with Node and run your tests!
+
+__Note:__ To create a _Debug_ build of the bindings file, pass the `--debug` (or
+`-d`) switch when running either the `configure`, `build` or `rebuild` command.
+
+
+The "binding.gyp" file
+----------------------
+
+Previously when node had `node-waf` you had to write a `wscript` file. The
+replacement for that is the `binding.gyp` file, which describes the configuration
+to build your module in a JSON-like format. This file gets placed in the root of
+your package, alongside the `package.json` file.
+
+A barebones `gyp` file appropriate for building a node addon looks like:
+
+``` python
+{
+  "targets": [
+    {
+      "target_name": "binding",
+      "sources": [ "src/binding.cc" ]
+    }
+  ]
+}
+```
+
+Some additional resources for addons and writing `gyp` files:
+
+ * ["Going Native" a nodeschool.io tutorial](http://nodeschool.io/#goingnative)
+ * ["Hello World" node addon example](https://github.com/nodejs/node/tree/master/test/addons/hello-world)
+ * [gyp user documentation](https://gyp.gsrc.io/docs/UserDocumentation.md)

+| `--tarball=$path`                 | Get headers from a local tarball
+| `--devdir=$path`                  | SDK download directory (default=~/.node-gyp)
+| `--ensure`                        | Don't reinstall headers if already present

+
+Configuration
+--------
+
+__`node-gyp` responds to environment variables or `npm` configuration__
+1. Environment variables take the form `npm_config_OPTION_NAME` for any of the 
+ options listed above (dashes in option names should be replaced by underscores).
+ These work also when `node-gyp` is invoked directly:  
+ `$ export npm_config_devdir=/tmp/.gyp`  
+ or on Windows  
+ `> set npm_config_devdir=c:\temp\.gyp`  
+2. As `npm` configuration, variables take the form `OPTION_NAME`.
+ This way only works when `node-gyp` is executed by `npm`:  
+ `$ npm config set [--global] devdir /tmp/.gyp`  
+ `$ npm i buffertools`

+This script is intended for use as a GYP_GENERATOR. It takes as input (by way of
+the generator flag config_path) the path of a json file that dictates the files
+and targets to search for. The following keys are supported:
+files: list of paths (relative) of the files to search for.
+test_targets: unqualified target names to search for. Any target in this list
+that depends upon a file in |files| is output regardless of the type of target
+or chain of dependencies.
+additional_compile_targets: Unqualified targets to search for in addition to
+test_targets. Targets in the combined list that depend upon a file in |files|
+are not necessarily output. For example, if the target is of type none then the
+target is not output (but one of the descendants of the target will be).
+
+The following is output:
+error: only supplied if there is an error.
+compile_targets: minimal set of targets that directly or indirectly (for
+  targets of type none) depend on the files in |files| and is one of the
+  supplied targets or a target that one of the supplied targets depends on.
+  The expectation is this set of targets is passed into a build step. This list
+  always contains the output of test_targets as well.
+test_targets: set of targets from the supplied |test_targets| that either
+  directly or indirectly depend upon a file in |files|. This list if useful
+  if additional processing needs to be done for certain targets after the
+  build, such as running tests.
+status: outputs one of three values: none of the supplied files were found,
+  one of the include files changed so that it should be assumed everything
+  changed (in this case test_targets and compile_targets are not output) or at
+  least one file was found.
+invalid_targets: list of supplied targets that were not found.
+
+Example:
+Consider a graph like the following:
+  A     D
+ / \
+B   C
+A depends upon both B and C, A is of type none and B and C are executables.
+D is an executable, has no dependencies and nothing depends on it.
+If |additional_compile_targets| = ["A"], |test_targets| = ["B", "C"] and
+files = ["b.cc", "d.cc"] (B depends upon b.cc and D depends upon d.cc), then
+the following is output:
+|compile_targets| = ["B"] B must built as it depends upon the changed file b.cc
+and the supplied target A depends upon it. A is not output as a build_target
+as it is of type none with no rules and actions.
+|test_targets| = ["B"] B directly depends upon the change file b.cc.
+
+Even though the file d.cc, which D depends upon, has changed D is not output
+as it was not supplied by way of |additional_compile_targets| or |test_targets|.
+
+If the generator flag analyzer_output_path is specified, output is written
+there. Otherwise output is written to stdout.
+
+In Gyp the "all" target is shorthand for the root targets in the files passed
+to gyp. For example, if file "a.gyp" contains targets "a1" and
+"a2", and file "b.gyp" contains targets "b1" and "b2" and "a2" has a dependency
+on "b2" and gyp is supplied "a.gyp" then "all" consists of "a1" and "a2".
+Notice that "b1" and "b2" are not in the "all" target as "b.gyp" was not
+directly supplied to gyp. OTOH if both "a.gyp" and "b.gyp" are supplied to gyp
+then the "all" target includes "b1" and "b2".

+"""cmake output module
+
+This module is under development and should be considered experimental.
+
+This module produces cmake (2.8.8+) input as its output. One CMakeLists.txt is
+created for each configuration.
+
+This module's original purpose was to support editing in IDEs like KDevelop
+which use CMake for project management. It is also possible to use CMake to
+generate projects for other IDEs such as eclipse cdt and code::blocks. QtCreator
+will convert the CMakeLists.txt to a code::blocks cbp for the editor to read,
+but build using CMake. As a result QtCreator editor is unaware of compiler
+defines. The generated CMakeLists.txt can also be used to build on Linux. There
+is currently no support for building on platforms other than Linux.
+
+The generated CMakeLists.txt should properly compile all projects. However,
+there is a mismatch between gyp and cmake with regard to linking. All attempts
+are made to work around this, but CMake sometimes sees -Wl,--start-group as a
+library and incorrectly repeats it. As a result the output of this generator
+should not be relied on for building.
+
+When using with kdevelop, use version 4.4+. Previous versions of kdevelop will
+not be able to find the header file directories described in the generated
+CMakeLists.txt file.

+"""GYP backend that generates Eclipse CDT settings files.
+
+This backend DOES NOT generate Eclipse CDT projects. Instead, it generates XML
+files that can be imported into an Eclipse CDT project. The XML file contains a
+list of include paths and symbols (i.e. defines).
+
+Because a full .cproject definition is not created by this generator, it's not
+possible to properly define the include dirs and symbols for each file
+individually.  Instead, one set of includes/symbols is generated for the entire
+project.  This works fairly well (and is a vast improvement in general), but may
+still result in a few indexer issues here and there.
+
+This generator has no automated tests, so expect it to be broken.

+"""gypd output module
+
+This module produces gyp input as its output.  Output files are given the
+.gypd extension to avoid overwriting the .gyp files that they are generated
+from.  Internal references to .gyp files (such as those found in
+"dependencies" sections) are not adjusted to point to .gypd files instead;
+unlike other paths, which are relative to the .gyp or .gypd file, such paths
+are relative to the directory from which gyp was run to create the .gypd file.
+
+This generator module is intended to be a sample and a debugging aid, hence
+the "d" for "debug" in .gypd.  It is useful to inspect the results of the
+various merges, expansions, and conditional evaluations performed by gyp
+and to see a representation of what would be fed to a generator module.
+
+It's not advisable to rename .gypd files produced by this module to .gyp,
+because they will have all merges, expansions, and evaluations already
+performed and the relevant constructs not present in the output; paths to
+dependencies may be wrong; and various sections that do not belong in .gyp
+files such as such as "included_files" and "*_excluded" will be present.
+Output will also be stripped of comments.  This is not intended to be a
+general-purpose gyp pretty-printer; for that, you probably just want to
+run "pprint.pprint(eval(open('source.gyp').read()))", which will still strip
+comments but won't do all of the other things done to this module's output.
+
+The specific formatting of the output generated by this module is subject
+to change.

+"""Xcode project file generator.
+
+This module is both an Xcode project file generator and a documentation of the
+Xcode project file format.  Knowledge of the project file format was gained
+based on extensive experience with Xcode, and by making changes to projects in
+Xcode.app and observing the resultant changes in the associated project files.
+
+XCODE PROJECT FILES
+
+The generator targets the file format as written by Xcode 3.2 (specifically,
+3.2.6), but past experience has taught that the format has not changed
+significantly in the past several years, and future versions of Xcode are able
+to read older project files.
+
+Xcode project files are "bundled": the project "file" from an end-user's
+perspective is actually a directory with an ".xcodeproj" extension.  The
+project file from this module's perspective is actually a file inside this
+directory, always named "project.pbxproj".  This file contains a complete
+description of the project and is all that is needed to use the xcodeproj.
+Other files contained in the xcodeproj directory are simply used to store
+per-user settings, such as the state of various UI elements in the Xcode
+application.
+
+The project.pbxproj file is a property list, stored in a format almost
+identical to the NeXTstep property list format.  The file is able to carry
+Unicode data, and is encoded in UTF-8.  The root element in the property list
+is a dictionary that contains several properties of minimal interest, and two
+properties of immense interest.  The most important property is a dictionary
+named "objects".  The entire structure of the project is represented by the
+children of this property.  The objects dictionary is keyed by unique 96-bit
+values represented by 24 uppercase hexadecimal characters.  Each value in the
+objects dictionary is itself a dictionary, describing an individual object.
+
+Each object in the dictionary is a member of a class, which is identified by
+the "isa" property of each object.  A variety of classes are represented in a
+project file.  Objects can refer to other objects by ID, using the 24-character
+hexadecimal object key.  A project's objects form a tree, with a root object
+of class PBXProject at the root.  As an example, the PBXProject object serves
+as parent to an XCConfigurationList object defining the build configurations
+used in the project, a PBXGroup object serving as a container for all files
+referenced in the project, and a list of target objects, each of which defines
+a target in the project.  There are several different types of target object,
+such as PBXNativeTarget and PBXAggregateTarget.  In this module, this
+relationship is expressed by having each target type derive from an abstract
+base named XCTarget.
+
+The project.pbxproj file's root dictionary also contains a property, sibling to
+the "objects" dictionary, named "rootObject".  The value of rootObject is a
+24-character object key referring to the root PBXProject object in the
+objects dictionary.
+
+In Xcode, every file used as input to a target or produced as a final product
+of a target must appear somewhere in the hierarchy rooted at the PBXGroup
+object referenced by the PBXProject's mainGroup property.  A PBXGroup is
+generally represented as a folder in the Xcode application.  PBXGroups can
+contain other PBXGroups as well as PBXFileReferences, which are pointers to
+actual files.
+
+Each XCTarget contains a list of build phases, represented in this module by
+the abstract base XCBuildPhase.  Examples of concrete XCBuildPhase derivations
+are PBXSourcesBuildPhase and PBXFrameworksBuildPhase, which correspond to the
+"Compile Sources" and "Link Binary With Libraries" phases displayed in the
+Xcode application.  Files used as input to these phases (for example, source
+files in the former case and libraries and frameworks in the latter) are
+represented by PBXBuildFile objects, referenced by elements of "files" lists
+in XCTarget objects.  Each PBXBuildFile object refers to a PBXBuildFile
+object as a "weak" reference: it does not "own" the PBXBuildFile, which is
+owned by the root object's mainGroup or a descendant group.  In most cases, the
+layer of indirection between an XCBuildPhase and a PBXFileReference via a
+PBXBuildFile appears extraneous, but there's actually one reason for this:
+file-specific compiler flags are added to the PBXBuildFile object so as to
+allow a single file to be a member of multiple targets while having distinct
+compiler flags for each.  These flags can be modified in the Xcode applciation
+in the "Build" tab of a File Info window.
+
+When a project is open in the Xcode application, Xcode will rewrite it.  As
+such, this module is careful to adhere to the formatting used by Xcode, to
+avoid insignificant changes appearing in the file when it is used in the
+Xcode application.  This will keep version control repositories happy, and
+makes it possible to compare a project file used in Xcode to one generated by
+this module to determine if any significant changes were made in the
+application.
+
+Xcode has its own way of assigning 24-character identifiers to each object,
+which is not duplicated here.  Because the identifier only is only generated
+once, when an object is created, and is then left unchanged, there is no need
+to attempt to duplicate Xcode's behavior in this area.  The generator is free
+to select any identifier, even at random, to refer to the objects it creates,
+and Xcode will retain those identifiers and use them when subsequently
+rewriting the project file.  However, the generator would choose new random
+identifiers each time the project files are generated, leading to difficulties
+comparing "used" project files to "pristine" ones produced by this module,
+and causing the appearance of changes as every object identifier is changed
+when updated projects are checked in to a version control repository.  To
+mitigate this problem, this module chooses identifiers in a more deterministic
+way, by hashing a description of each object as well as its parent and ancestor
+objects.  This strategy should result in minimal "shift" in IDs as successive
+generations of project files are produced.
+
+THIS MODULE
+
+This module introduces several classes, all derived from the XCObject class.
+Nearly all of the "brains" are built into the XCObject class, which understands
+how to create and modify objects, maintain the proper tree structure, compute
+identifiers, and print objects.  For the most part, classes derived from
+XCObject need only provide a _schema class object, a dictionary that
+expresses what properties objects of the class may contain.
+
+Given this structure, it's possible to build a minimal project file by creating
+objects of the appropriate types and making the proper connections:
+
+  config_list = XCConfigurationList()
+  group = PBXGroup()
+  project = PBXProject({'buildConfigurationList': config_list,
+                        'mainGroup': group})
+
+With the project object set up, it can be added to an XCProjectFile object.
+XCProjectFile is a pseudo-class in the sense that it is a concrete XCObject
+subclass that does not actually correspond to a class type found in a project
+file.  Rather, it is used to represent the project file's root dictionary.
+Printing an XCProjectFile will print the entire project file, including the
+full "objects" dictionary.
+
+  project_file = XCProjectFile({'rootObject': project})
+  project_file.ComputeIDs()
+  project_file.Print()
+
+Xcode project files are always encoded in UTF-8.  This module will accept
+strings of either the str class or the unicode class.  Strings of class str
+are assumed to already be encoded in UTF-8.  Obviously, if you're just using
+ASCII, you won't encounter difficulties because ASCII is a UTF-8 subset.
+Strings of class unicode are handled properly and encoded in UTF-8 when
+a project file is output.

+             are a list of four or five elements:

+             property_type: The type to use as the value of the property,
+                            or if is_list is True, the type to use for each
+                            element of the value's list.  property_type must

+             is_strong: If property_type is an XCObject subclass, is_strong
+                        is True to assert that this class "owns," or serves
+                        as parent, to the property value (or, if is_list is
+                        True, values).  is_strong must be False if
+                        property_type is not an XCObject subclass.
+             is_required: True if the property is required for the class.
+                          Note that is_required being True does not preclude
+                          an empty string ("", in the case of property_type
+                          str) or list ([], in the case of is_list True) from
+                          being set for the property.
+             default: Optional.  If is_requried is True, default may be set
+                      to provide a default value for objects that do not supply
+                      their own value.  If is_required is True and default
+                      is not provided, users of the class must supply their own
+                      value for the property.
+             Note that although the values of the array are expressed in
+             boolean terms, subclasses provide values as integers to conserve
+             horizontal space.
+    _should_print_single_line: False in XCObject.  Subclasses whose objects
+                               should be written to the project file in the
+                               alternate single-line format, such as
+                               PBXFileReference and PBXBuildFile, should
+                               set this to True.
+    _encode_transforms: Used by _EncodeString to encode unprintable characters.
+                        The index into this list is the ordinal of the
+                        character to transform; each value is a string
+                        used to represent the character in the output.  XCObject
+                        provides an _encode_transforms list suitable for most
+                        XCObject subclasses.
+    _alternate_encode_transforms: Provided for subclasses that wish to use
+                                  the alternate encoding rules.  Xcode seems
+                                  to use these rules when printing objects in
+                                  single-line format.  Subclasses that desire
+                                  this behavior should set _encode_transforms
+                                  to _alternate_encode_transforms.
+    _hashables: A list of XCObject subclasses that can be hashed by ComputeIDs
+                to construct this object's ID.  Most classes that need custom
+                hashing behavior should do it by overriding Hashables,
+                but in some cases an object's parent may wish to push a

+                to _hashables.
+  Attributes:
+    id: The object's identifier, a 24-character uppercase hexadecimal string.
+        Usually, objects being created should not set id until the entire

+        be called on the root object to assign deterministic values for id to
+        each object in the tree.
+    parent: The object's parent.  This is set by a parent XCObject when a child
+            object is added to it.

+
+    XCHierarchicalElements are special.  Generally, their hashes shouldn't
+    change if the paths don't change.  The normal XCObject implementation of
+    Hashables adds a hashable for each object, which means that if
+    the hierarchical structure changes (possibly due to changes caused when
+    TakeOverOnlyChild runs and encounters slight changes in the hierarchy),
+    the hashes will change.  For example, if a project file initially contains
+    a/b/f1 and a/b becomes collapsed into a/b, f1 will have a single parent
+    a/b.  If someone later adds a/f2 to the project file, a/b can no longer be
+    collapsed, and f1 winds up with parent b and grandparent a.  That would
+    be sufficient to change f1's hash.
+
+    To counteract this problem, hashables for all XCHierarchicalElements except
+    for the main group (which has neither a name nor a path) are taken to be
+    just the set of path components.  Because hashables are inherited from
+    parents, this provides assurance that a/b/f1 has the same set of hashables
+    whether its parent is b or a/b.
+
+    The main group is a special case.  As it is permitted to have no name or
+    path, it is permitted to use the standard XCObject hash mechanism.  This
+    is not considered a problem because there can be only one main group.

+If you want to write an option parser, and have it be good, there are
+two ways to do it.  The Right Way, and the Wrong Way.
+
+The Wrong Way is to sit down and write an option parser.  We've all done
+that.
+
+The Right Way is to write some complex configurable program with so many
+options that you hit the limit of your frustration just trying to
+manage them all, and defer it with duct-tape solutions until you see
+exactly to the core of the problem, and finally snap and write an
+awesome option parser.
+
+If you want to write an option parser, don't write an option parser.
+Write a package manager, or a source control system, or a service
+restarter, or an operating system.  You probably won't end up with a
+good one of those, but if you don't give up, and you are relentless and
+diligent enough in your procrastination, you may just end up with a very
+nice option parser.
+
+## USAGE
+
+    // my-program.js
+    var nopt = require("nopt")
+      , Stream = require("stream").Stream
+      , path = require("path")
+      , knownOpts = { "foo" : [String, null]
+                    , "bar" : [Stream, Number]
+                    , "baz" : path
+                    , "bloo" : [ "big", "medium", "small" ]
+                    , "flag" : Boolean
+                    , "pick" : Boolean
+                    , "many1" : [String, Array]
+                    , "many2" : [path]
+                    }
+      , shortHands = { "foofoo" : ["--foo", "Mr. Foo"]
+                     , "b7" : ["--bar", "7"]
+                     , "m" : ["--bloo", "medium"]
+                     , "p" : ["--pick"]
+                     , "f" : ["--flag"]
+                     }
+                 // everything is optional.
+                 // knownOpts and shorthands default to {}
+                 // arg list defaults to process.argv
+                 // slice defaults to 2
+      , parsed = nopt(knownOpts, shortHands, process.argv, 2)
+    console.log(parsed)
+
+This would give you support for any of the following:
+
+```bash
+$ node my-program.js --foo "blerp" --no-flag
+{ "foo" : "blerp", "flag" : false }
+
+$ node my-program.js ---bar 7 --foo "Mr. Hand" --flag
+{ bar: 7, foo: "Mr. Hand", flag: true }
+
+$ node my-program.js --foo "blerp" -f -----p
+{ foo: "blerp", flag: true, pick: true }
+
+$ node my-program.js -fp --foofoo
+{ foo: "Mr. Foo", flag: true, pick: true }
+
+$ node my-program.js --foofoo -- -fp  # -- stops the flag parsing.
+{ foo: "Mr. Foo", argv: { remain: ["-fp"] } }
+
+$ node my-program.js --blatzk -fp # unknown opts are ok.
+{ blatzk: true, flag: true, pick: true }
+
+$ node my-program.js --blatzk=1000 -fp # but you need to use = if they have a value
+{ blatzk: 1000, flag: true, pick: true }
+
+$ node my-program.js --no-blatzk -fp # unless they start with "no-"
+{ blatzk: false, flag: true, pick: true }
+
+$ node my-program.js --baz b/a/z # known paths are resolved.

+```
+
+Read the tests at the bottom of `lib/nopt.js` for more examples of
+what this puppy can do.
+
+## Types
+
+The following types are supported, and defined on `nopt.typeDefs`
+
+* String: A normal string.  No parsing is done.
+* path: A file system path.  Gets resolved against cwd if not absolute.
+* url: A url.  If it doesn't parse, it isn't accepted.
+* Number: Must be numeric.
+* Date: Must parse as a date. If it does, and `Date` is one of the options,
+  then it will return a Date object, not a string.
+* Boolean: Must be either `true` or `false`.  If an option is a boolean,
+  then it does not need a value, and its presence will imply `true` as
+  the value.  To negate boolean flags, do `--no-whatever` or `--whatever
+  false`
+* NaN: Means that the option is strictly not allowed.  Any value will
+  fail.
+* Stream: An object matching the "Stream" class in node.  Valuable
+  for use when validating programmatically.  (npm uses this to let you
+  supply any WriteStream on the `outfd` and `logfd` config options.)
+* Array: If `Array` is specified as one of the types, then the value
+  will be parsed as a list of options.  This means that multiple values
+  can be specified, and that the value will always be an array.
+
+If a type is an array of values not on this list, then those are
+considered valid values.  For instance, in the example above, the
+`--bloo` option can only be one of `"big"`, `"medium"`, or `"small"`,
+and any other value will be rejected.
+
+When parsing unknown fields, `"true"`, `"false"`, and `"null"` will be
+interpreted as their JavaScript equivalents.
+
+You can also mix types and values, or multiple types, in a list.  For
+instance `{ blah: [Number, null] }` would allow a value to be set to
+either a Number or null.  When types are ordered, this implies a
+preference, and the first type that can be used to properly interpret
+the value will be used.
+
+To define a new type, add it to `nopt.typeDefs`.  Each item in that
+hash is an object with a `type` member and a `validate` method.  The
+`type` member is an object that matches what goes in the type list.  The
+`validate` method is a function that gets called with `validate(data,
+key, val)`.  Validate methods should assign `data[key]` to the valid
+value of `val` if it can be handled properly, or return boolean
+`false` if it cannot.
+
+You can also call `nopt.clean(data, types, typeDefs)` to clean up a
+config object and remove its invalid properties.
+
+## Error Handling
+
+By default, nopt outputs a warning to standard error when invalid values for
+known options are found.  You can change this behavior by assigning a method
+to `nopt.invalidHandler`.  This method will be called with
+the offending `nopt.invalidHandler(key, val, types)`.
+
+If no `nopt.invalidHandler` is assigned, then it will console.error
+its whining.  If it is assigned to boolean `false` then the warning is
+suppressed.
+
+## Abbreviations
+
+Yes, they are supported.  If you define options like this:
+
+```javascript
+{ "foolhardyelephants" : Boolean
+, "pileofmonkeys" : Boolean }
+```
+
+Then this will work:
+
+```bash
+node program.js --foolhar --pil
+node program.js --no-f --pileofmon
+# etc.
+```
+
+## Shorthands
+
+Shorthands are a hash of shorter option names to a snippet of args that
+they expand to.
+
+If multiple one-character shorthands are all combined, and the
+combination does not unambiguously match any other option or shorthand,
+then they will be broken up into their constituent parts.  For example:
+
+```json
+{ "s" : ["--loglevel", "silent"]
+, "g" : "--global"
+, "f" : "--force"
+, "p" : "--parseable"
+, "l" : "--long"
+}
+```
+
+```bash
+npm ls -sgflp
+# just like doing this:
+npm ls --loglevel silent --global --force --long --parseable
+```
+
+## The Rest of the args
+
+The config object returned by nopt is given a special member called
+`argv`, which is an object with the following fields:
+
+* `remain`: The remaining args after all the parsing has occurred.
+* `original`: The args as they originally appeared.
+* `cooked`: The args after flags and shorthands are expanded.
+
+## Slicing
+
+Node programs are called with more or less the exact argv as it appears
+in C land, after the v8 and node-specific options have been plucked off.
+As such, `argv[0]` is always `node` and `argv[1]` is always the
+JavaScript program being run.
+
+That's usually not very useful to you.  So they're sliced off by
+default.  If you want them, then you can pass in `0` as the last
+argument, or any other number that you'd like to slice off the start of
+the list.

+# [2.0.0](https://github.com/npm/lifecycle/compare/v1.0.3...v2.0.0) (2017-11-17)
+
+
+### Features
+
+* **node-gyp:** use own node-gyp ([ae94ed2](https://github.com/npm/lifecycle/commit/ae94ed2))
+* **nodeOptions:** add "nodeOptions" option to set NODE_OPTIONS for child ([#7](https://github.com/npm/lifecycle/issues/7)) ([2eb7a38](https://github.com/npm/lifecycle/commit/2eb7a38))
+* **stdio:** add child process io options and default logging of piped stdout/err ([#3](https://github.com/npm/lifecycle/issues/3)) ([7b8281a](https://github.com/npm/lifecycle/commit/7b8281a))
+
+
+### BREAKING CHANGES
+
+* **node-gyp:** Previously you had to bring your own node-gyp AND you had
+to provide access the way npm does, by having a `bin` dir with a
+`node-gyp-bin` in it.
+
+Fixes: #4

+The Artistic License 2.0
+
+Copyright (c) 2000-2006, The Perl Foundation.
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+
+Preamble
+
+This license establishes the terms under which a given free software
+Package may be copied, modified, distributed, and/or redistributed.
+The intent is that the Copyright Holder maintains some artistic
+control over the development of that Package while still keeping the
+Package available as open source and free software.
+
+You are always permitted to make arrangements wholly outside of this
+license directly with the Copyright Holder of a given Package.  If the
+terms of this license do not permit the full use that you propose to
+make of the Package, you should contact the Copyright Holder and seek
+a different licensing arrangement.
+
+Definitions
+
+    "Copyright Holder" means the individual(s) or organization(s)
+    named in the copyright notice for the entire Package.
+
+    "Contributor" means any party that has contributed code or other
+    material to the Package, in accordance with the Copyright Holder's
+    procedures.
+
+    "You" and "your" means any person who would like to copy,
+    distribute, or modify the Package.
+
+    "Package" means the collection of files distributed by the
+    Copyright Holder, and derivatives of that collection and/or of
+    those files. A given Package may consist of either the Standard
+    Version, or a Modified Version.
+
+    "Distribute" means providing a copy of the Package or making it
+    accessible to anyone else, or in the case of a company or
+    organization, to others outside of your company or organization.
+
+    "Distributor Fee" means any fee that you charge for Distributing
+    this Package or providing support for this Package to another
+    party.  It does not mean licensing fees.
+
+    "Standard Version" refers to the Package if it has not been
+    modified, or has been modified only in ways explicitly requested
+    by the Copyright Holder.
+
+    "Modified Version" means the Package, if it has been changed, and
+    such changes were not explicitly requested by the Copyright
+    Holder.
+
+    "Original License" means this Artistic License as Distributed with
+    the Standard Version of the Package, in its current version or as
+    it may be modified by The Perl Foundation in the future.
+
+    "Source" form means the source code, documentation source, and
+    configuration files for the Package.
+
+    "Compiled" form means the compiled bytecode, object code, binary,
+    or any other form resulting from mechanical transformation or
+    translation of the Source form.
+
+
+Permission for Use and Modification Without Distribution
+
+(1)  You are permitted to use the Standard Version and create and use
+Modified Versions for any purpose without restriction, provided that
+you do not Distribute the Modified Version.
+
+
+Permissions for Redistribution of the Standard Version
+
+(2)  You may Distribute verbatim copies of the Source form of the
+Standard Version of this Package in any medium without restriction,
+either gratis or for a Distributor Fee, provided that you duplicate
+all of the original copyright notices and associated disclaimers.  At
+your discretion, such verbatim copies may or may not include a
+Compiled form of the Package.
+
+(3)  You may apply any bug fixes, portability changes, and other
+modifications made available from the Copyright Holder.  The resulting
+Package will still be considered the Standard Version, and as such
+will be subject to the Original License.
+
+
+Distribution of Modified Versions of the Package as Source
+
+(4)  You may Distribute your Modified Version as Source (either gratis
+or for a Distributor Fee, and with or without a Compiled form of the
+Modified Version) provided that you clearly document how it differs
+from the Standard Version, including, but not limited to, documenting
+any non-standard features, executables, or modules, and provided that
+you do at least ONE of the following:
+
+    (a)  make the Modified Version available to the Copyright Holder
+    of the Standard Version, under the Original License, so that the
+    Copyright Holder may include your modifications in the Standard
+    Version.
+
+    (b)  ensure that installation of your Modified Version does not
+    prevent the user installing or running the Standard Version. In
+    addition, the Modified Version must bear a name that is different
+    from the name of the Standard Version.
+
+    (c)  allow anyone who receives a copy of the Modified Version to
+    make the Source form of the Modified Version available to others
+    under
+
+        (i)  the Original License or
+
+        (ii)  a license that permits the licensee to freely copy,
+        modify and redistribute the Modified Version using the same
+        licensing terms that apply to the copy that the licensee
+        received, and requires that the Source form of the Modified
+        Version, and of any works derived from it, be made freely
+        available in that license fees are prohibited but Distributor
+        Fees are allowed.
+
+
+Distribution of Compiled Forms of the Standard Version
+or Modified Versions without the Source
+
+(5)  You may Distribute Compiled forms of the Standard Version without
+the Source, provided that you include complete instructions on how to
+get the Source of the Standard Version.  Such instructions must be
+valid at the time of your distribution.  If these instructions, at any
+time while you are carrying out such distribution, become invalid, you
+must provide new instructions on demand or cease further distribution.
+If you provide valid instructions or cease distribution within thirty
+days after you become aware that the instructions are invalid, then
+you do not forfeit any of your rights under this license.
+
+(6)  You may Distribute a Modified Version in Compiled form without
+the Source, provided that you comply with Section 4 with respect to
+the Source of the Modified Version.
+
+
+Aggregating or Linking the Package
+
+(7)  You may aggregate the Package (either the Standard Version or
+Modified Version) with other packages and Distribute the resulting
+aggregation provided that you do not charge a licensing fee for the
+Package.  Distributor Fees are permitted, and licensing fees for other
+components in the aggregation are permitted. The terms of this license
+apply to the use and Distribution of the Standard or Modified Versions
+as included in the aggregation.
+
+(8) You are permitted to link Modified and Standard Versions with
+other works, to embed the Package in a larger work of your own, or to
+build stand-alone binary or bytecode versions of applications that
+include the Package, and Distribute the result without restriction,
+provided the result does not expose a direct interface to the Package.
+
+
+Items That are Not Considered Part of a Modified Version
+
+(9) Works (including, but not limited to, modules and scripts) that
+merely extend or make use of the Package, do not, by themselves, cause
+the Package to be a Modified Version.  In addition, such works are not
+considered parts of the Package itself, and are not subject to the
+terms of this license.
+
+
+General Provisions
+
+(10)  Any use, modification, and distribution of the Standard or
+Modified Versions is governed by this Artistic License. By using,
+modifying or distributing the Package, you accept this license. Do not
+use, modify, or distribute the Package, if you do not accept this
+license.
+
+(11)  If your Modified Version has been derived from a Modified
+Version made by someone other than you, you are nevertheless required
+to ensure that your Modified Version complies with the requirements of
+this license.
+
+(12)  This license does not grant you the right to use any trademark,
+service mark, tradename, or logo of the Copyright Holder.
+
+(13)  This license includes the non-exclusive, worldwide,
+free-of-charge patent license to make, have made, use, offer to sell,
+sell, import and otherwise transfer the Package with respect to any
+patent claims licensable by the Copyright Holder that are necessarily
+infringed by the Package. If you institute patent litigation
+(including a cross-claim or counterclaim) against any party alleging
+that the Package constitutes direct or contributory patent
+infringement, then this Artistic License to you shall terminate on the
+date that such litigation is filed.
+
+(14)  Disclaimer of Warranty:
+THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS
+IS' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. THE IMPLIED
+WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR
+NON-INFRINGEMENT ARE DISCLAIMED TO THE EXTENT PERMITTED BY YOUR LOCAL
+LAW. UNLESS REQUIRED BY LAW, NO COPYRIGHT HOLDER OR CONTRIBUTOR WILL
+BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
+DAMAGES ARISING IN ANY WAY OUT OF THE USE OF THE PACKAGE, EVEN IF
+ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Usage
+
+    $ npm install semver
+    $ node
+    var semver = require('semver')
+
+    semver.valid('1.2.3') // '1.2.3'
+    semver.valid('a.b.c') // null
+    semver.clean('  =v1.2.3   ') // '1.2.3'
+    semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+    semver.gt('1.2.3', '9.8.7') // false
+    semver.lt('1.2.3', '9.8.7') // true
+
+As a command-line utility:
+
+    $ semver -h
+
+    SemVer 5.1.0
+
+    A JavaScript implementation of the http://semver.org/ specification
+    Copyright Isaac Z. Schlueter
+
+    Usage: semver [options] <version> [<version> [...]]
+    Prints valid versions sorted by SemVer precedence
+
+    Options:
+    -r --range <range>
+            Print versions that match the specified range.
+
+    -i --increment [<level>]
+            Increment a version by the specified level.  Level can
+            be one of: major, minor, patch, premajor, preminor,
+            prepatch, or prerelease.  Default level is 'patch'.
+            Only one version may be specified.
+
+    --preid <identifier>
+            Identifier to be used to prefix premajor, preminor,
+            prepatch or prerelease version increments.
+
+    -l --loose
+            Interpret versions and ranges loosely
+
+    Program exits successfully if any valid version satisfies
+    all supplied ranges, and prints all satisfying versions.
+
+    If no satisfying versions are found, then exits failure.
+
+    Versions are printed in ascending order, so supplying
+    multiple versions to the utility will just sort them.
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<http://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.  The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+> semver.inc('1.2.3', 'prerelease', 'beta')
+'1.2.4-beta.0'
+```
+
+command-line example:
+
+```shell
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```shell
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any version satisfies)
+* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero digit in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0`
+* `^0.2.3` := `>=0.2.3 <0.3.0`
+* `^0.0.3` := `>=0.0.3 <0.0.4`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0`
+* `^0.0.x` := `>=0.0.0 <0.1.0`
+* `^0.0` := `>=0.0.0 <0.1.0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0`
+* `^0.x` := `>=0.0.0 <1.0.0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' | ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde      ::= '~' partial
+caret      ::= '^' partial
+qualifier  ::= ( '-' pre )? ( '+' build )?
+pre        ::= parts
+build      ::= parts
+parts      ::= part ( '.' part ) *
+part       ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `loose` boolean argument that, if
+true, will be more forgiving about not-quite-valid semver strings.
+The resulting output will always be 100% strict, of course.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, or `prerelease`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, the `prerelease` will work the
+    same as `prepatch`. It increments the patch version, then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the exact same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.

+node-gyp
+=========
+## Node.js native addon build tool
+
+`node-gyp` is a cross-platform command-line tool written in Node.js for compiling
+native addon modules for Node.js.  It bundles the [gyp](https://gyp.gsrc.io)
+project used by the Chromium team and takes away the pain of dealing with the
+various differences in build platforms. It is the replacement to the `node-waf`
+program which is removed for node `v0.8`. If you have a native addon for node that
+still has a `wscript` file, then you should definitely add a `binding.gyp` file
+to support the latest versions of node.
+
+Multiple target versions of node are supported (i.e. `0.8`, ..., `4`, `5`, `6`,
+etc.), regardless of what version of node is actually installed on your system
+(`node-gyp` downloads the necessary development files or headers for the target version).
+
+## Features
+
+ * Easy to use, consistent interface
+ * Same commands to build your module on every platform
+ * Supports multiple target versions of Node
+
+
+Installation
+------------
+
+You can install with `npm`:
+
+``` bash
+$ npm install -g node-gyp
+```
+
+You will also need to install:
+
+### On Unix
+
+   * `python` (`v2.7` recommended, `v3.x.x` is __*not*__ supported)
+   * `make`
+   * A proper C/C++ compiler toolchain, like [GCC](https://gcc.gnu.org)
+
+### On macOS
+
+   * `python` (`v2.7` recommended, `v3.x.x` is __*not*__ supported) (already installed on macOS)
+   * [Xcode](https://developer.apple.com/xcode/download/)
+     * You also need to install the `Command Line Tools` via Xcode. You can find this under the menu `Xcode -> Preferences -> Locations` (or by running `xcode-select --install` in your Terminal)
+       * This step will install `gcc` and the related toolchain containing `make`
+
+### On Windows
+
+#### Option 1
+
+Install all the required tools and configurations using Microsoft's [windows-build-tools](https://github.com/felixrieseberg/windows-build-tools) using `npm install --global --production windows-build-tools` from an elevated PowerShell or CMD.exe (run as Administrator).
+
+#### Option 2
+
+Install tools and configuration manually:
+   * Install Visual C++ Build Environment: [Visual Studio Build Tools](https://visualstudio.microsoft.com/thank-you-downloading-visual-studio/?sku=BuildTools)
+   (using "Visual C++ build tools" workload) or [Visual Studio 2017 Community](https://visualstudio.microsoft.com/pl/thank-you-downloading-visual-studio/?sku=Community)
+   (using the "Desktop development with C++" workload)
+   * Install [Python 2.7](https://www.python.org/downloads/) (`v3.x.x` is not supported), and run `npm config set python python2.7` (or see below for further instructions on specifying the proper Python version and path.)
+   * Launch cmd, `npm config set msvs_version 2017`
+
+   If the above steps didn't work for you, please visit [Microsoft's Node.js Guidelines for Windows](https://github.com/Microsoft/nodejs-guidelines/blob/master/windows-environment.md#compiling-native-addon-modules) for additional tips.
+
+If you have multiple Python versions installed, you can identify which Python
+version `node-gyp` uses by setting the '--python' variable:
+
+``` bash
+$ node-gyp --python /path/to/python2.7
+```
+
+If `node-gyp` is called by way of `npm` *and* you have multiple versions of
+Python installed, then you can set `npm`'s 'python' config key to the appropriate
+value:
+
+``` bash
+$ npm config set python /path/to/executable/python2.7
+```
+
+How to Use
+----------
+
+To compile your native addon, first go to its root directory:
+
+``` bash
+$ cd my_node_addon
+```
+
+The next step is to generate the appropriate project build files for the current
+platform. Use `configure` for that:
+
+``` bash
+$ node-gyp configure
+```
+
+Auto-detection fails for Visual C++ Build Tools 2015, so `--msvs_version=2015`
+needs to be added (not needed when run by npm as configured above):
+``` bash
+$ node-gyp configure --msvs_version=2015
+```
+
+__Note__: The `configure` step looks for the `binding.gyp` file in the current
+directory to process. See below for instructions on creating the `binding.gyp` file.
+
+Now you will have either a `Makefile` (on Unix platforms) or a `vcxproj` file
+(on Windows) in the `build/` directory. Next invoke the `build` command:
+
+``` bash
+$ node-gyp build
+```
+
+Now you have your compiled `.node` bindings file! The compiled bindings end up
+in `build/Debug/` or `build/Release/`, depending on the build mode. At this point
+you can require the `.node` file with Node and run your tests!
+
+__Note:__ To create a _Debug_ build of the bindings file, pass the `--debug` (or
+`-d`) switch when running either the `configure`, `build` or `rebuild` command.
+
+
+The "binding.gyp" file
+----------------------
+
+Previously when node had `node-waf` you had to write a `wscript` file. The
+replacement for that is the `binding.gyp` file, which describes the configuration
+to build your module in a JSON-like format. This file gets placed in the root of
+your package, alongside the `package.json` file.
+
+A barebones `gyp` file appropriate for building a node addon looks like:
+
+``` python
+{
+  "targets": [
+    {
+      "target_name": "binding",
+      "sources": [ "src/binding.cc" ]
+    }
+  ]
+}
+```
+
+Some additional resources for addons and writing `gyp` files:
+
+ * ["Going Native" a nodeschool.io tutorial](http://nodeschool.io/#goingnative)
+ * ["Hello World" node addon example](https://github.com/nodejs/node/tree/master/test/addons/hello-world)
+ * [gyp user documentation](https://gyp.gsrc.io/docs/UserDocumentation.md)
+ * [gyp input format reference](https://gyp.gsrc.io/docs/InputFormatReference.md)

+
+
+Commands
+--------
+
+`node-gyp` responds to the following commands:
+
+| **Command**   | **Description**
+|:--------------|:---------------------------------------------------------------
+| `help`        | Shows the help dialog
+| `build`       | Invokes `make`/`msbuild.exe` and builds the native addon
+| `clean`       | Removes the `build` directory if it exists
+| `configure`   | Generates project build files for the current platform
+| `rebuild`     | Runs `clean`, `configure` and `build` all in a row
+| `install`     | Installs node header files for the given version
+| `list`        | Lists the currently installed node header versions
+| `remove`      | Removes the node header files for the given version
+
+
+Command Options
+--------
+
+`node-gyp` accepts the following command options:
+
+| **Command**                       | **Description**
+|:----------------------------------|:------------------------------------------
+| `-j n`, `--jobs n`                | Run make in parallel
+| `--target=v6.2.1`                 | Node version to build for (default=process.version)
+| `--silly`, `--loglevel=silly`     | Log all progress to console
+| `--verbose`, `--loglevel=verbose` | Log most progress to console
+| `--silent`, `--loglevel=silent`   | Don't log anything to console
+| `debug`, `--debug`                | Make Debug build (default=Release)
+| `--release`, `--no-debug`         | Make Release build
+| `-C $dir`, `--directory=$dir`     | Run command in different directory
+| `--make=$make`                    | Override make command (e.g. gmake)
+| `--thin=yes`                      | Enable thin static libraries
+| `--arch=$arch`                    | Set target architecture (e.g. ia32)
+| `--tarball=$path`                 | Get headers from a local tarball
+| `--devdir=$path`                  | SDK download directory (default=~/.node-gyp)
+| `--ensure`                        | Don't reinstall headers if already present
+| `--dist-url=$url`                 | Download header tarball from custom URL
+| `--proxy=$url`                    | Set HTTP proxy for downloading header tarball
+| `--cafile=$cafile`                | Override default CA chain (to download tarball)
+| `--nodedir=$path`                 | Set the path to the node source code
+| `--python=$path`                  | Set path to the python (2) binary
+| `--msvs_version=$version`         | Set Visual Studio version (win)
+| `--solution=$solution`            | Set Visual Studio Solution version (win)
+
+
+Configuration
+--------
+
+__`node-gyp` responds to environment variables or `npm` configuration__
+1. Environment variables take the form `npm_config_OPTION_NAME` for any of the 
+ options listed above (dashes in option names should be replaced by underscores).
+ These work also when `node-gyp` is invoked directly:  
+ `$ export npm_config_devdir=/tmp/.gyp`  
+ or on Windows  
+ `> set npm_config_devdir=c:\temp\.gyp`  
+2. As `npm` configuration, variables take the form `OPTION_NAME`.
+ This way only works when `node-gyp` is executed by `npm`:  
+ `$ npm config set [--global] devdir /tmp/.gyp`  
+ `$ npm i buffertools`

+This script is intended for use as a GYP_GENERATOR. It takes as input (by way of

+and targets to search for. The following keys are supported:
+files: list of paths (relative) of the files to search for.
+test_targets: unqualified target names to search for. Any target in this list
+that depends upon a file in |files| is output regardless of the type of target
+or chain of dependencies.
+additional_compile_targets: Unqualified targets to search for in addition to
+test_targets. Targets in the combined list that depend upon a file in |files|
+are not necessarily output. For example, if the target is of type none then the
+target is not output (but one of the descendants of the target will be).

+The following is output:
+error: only supplied if there is an error.
+compile_targets: minimal set of targets that directly or indirectly (for
+  targets of type none) depend on the files in |files| and is one of the
+  supplied targets or a target that one of the supplied targets depends on.
+  The expectation is this set of targets is passed into a build step. This list
+  always contains the output of test_targets as well.
+test_targets: set of targets from the supplied |test_targets| that either
+  directly or indirectly depend upon a file in |files|. This list if useful
+  if additional processing needs to be done for certain targets after the
+  build, such as running tests.
+status: outputs one of three values: none of the supplied files were found,
+  one of the include files changed so that it should be assumed everything
+  changed (in this case test_targets and compile_targets are not output) or at
+  least one file was found.
+invalid_targets: list of supplied targets that were not found.
+
+Example:
+Consider a graph like the following:
+  A     D
+ / \
+B   C
+A depends upon both B and C, A is of type none and B and C are executables.
+D is an executable, has no dependencies and nothing depends on it.
+If |additional_compile_targets| = ["A"], |test_targets| = ["B", "C"] and
+files = ["b.cc", "d.cc"] (B depends upon b.cc and D depends upon d.cc), then
+the following is output:
+|compile_targets| = ["B"] B must built as it depends upon the changed file b.cc
+and the supplied target A depends upon it. A is not output as a build_target
+as it is of type none with no rules and actions.
+|test_targets| = ["B"] B directly depends upon the change file b.cc.
+
+Even though the file d.cc, which D depends upon, has changed D is not output
+as it was not supplied by way of |additional_compile_targets| or |test_targets|.
+
+If the generator flag analyzer_output_path is specified, output is written
+there. Otherwise output is written to stdout.
+
+In Gyp the "all" target is shorthand for the root targets in the files passed
+to gyp. For example, if file "a.gyp" contains targets "a1" and
+"a2", and file "b.gyp" contains targets "b1" and "b2" and "a2" has a dependency
+on "b2" and gyp is supplied "a.gyp" then "all" consists of "a1" and "a2".
+Notice that "b1" and "b2" are not in the "all" target as "b.gyp" was not
+directly supplied to gyp. OTOH if both "a.gyp" and "b.gyp" are supplied to gyp
+then the "all" target includes "b1" and "b2".

+"""cmake output module
+
+This module is under development and should be considered experimental.
+
+This module produces cmake (2.8.8+) input as its output. One CMakeLists.txt is
+created for each configuration.
+
+This module's original purpose was to support editing in IDEs like KDevelop
+which use CMake for project management. It is also possible to use CMake to
+generate projects for other IDEs such as eclipse cdt and code::blocks. QtCreator
+will convert the CMakeLists.txt to a code::blocks cbp for the editor to read,
+but build using CMake. As a result QtCreator editor is unaware of compiler
+defines. The generated CMakeLists.txt can also be used to build on Linux. There
+is currently no support for building on platforms other than Linux.
+
+The generated CMakeLists.txt should properly compile all projects. However,
+there is a mismatch between gyp and cmake with regard to linking. All attempts
+are made to work around this, but CMake sometimes sees -Wl,--start-group as a
+library and incorrectly repeats it. As a result the output of this generator
+should not be relied on for building.
+
+When using with kdevelop, use version 4.4+. Previous versions of kdevelop will
+not be able to find the header file directories described in the generated
+CMakeLists.txt file.

+"""GYP backend that generates Eclipse CDT settings files.
+
+This backend DOES NOT generate Eclipse CDT projects. Instead, it generates XML
+files that can be imported into an Eclipse CDT project. The XML file contains a
+list of include paths and symbols (i.e. defines).
+
+Because a full .cproject definition is not created by this generator, it's not
+possible to properly define the include dirs and symbols for each file
+individually.  Instead, one set of includes/symbols is generated for the entire
+project.  This works fairly well (and is a vast improvement in general), but may
+still result in a few indexer issues here and there.
+
+This generator has no automated tests, so expect it to be broken.

+"""gypd output module
+
+This module produces gyp input as its output.  Output files are given the
+.gypd extension to avoid overwriting the .gyp files that they are generated
+from.  Internal references to .gyp files (such as those found in
+"dependencies" sections) are not adjusted to point to .gypd files instead;
+unlike other paths, which are relative to the .gyp or .gypd file, such paths
+are relative to the directory from which gyp was run to create the .gypd file.
+
+This generator module is intended to be a sample and a debugging aid, hence
+the "d" for "debug" in .gypd.  It is useful to inspect the results of the
+various merges, expansions, and conditional evaluations performed by gyp
+and to see a representation of what would be fed to a generator module.
+
+It's not advisable to rename .gypd files produced by this module to .gyp,
+because they will have all merges, expansions, and evaluations already
+performed and the relevant constructs not present in the output; paths to
+dependencies may be wrong; and various sections that do not belong in .gyp
+files such as such as "included_files" and "*_excluded" will be present.
+Output will also be stripped of comments.  This is not intended to be a
+general-purpose gyp pretty-printer; for that, you probably just want to
+run "pprint.pprint(eval(open('source.gyp').read()))", which will still strip
+comments but won't do all of the other things done to this module's output.
+
+The specific formatting of the output generated by this module is subject
+to change.

+    #         rule's output, giving it a dummy file it doesn't know how to
+    #         compile.  The rule action script would need to touch the dummy.

+"""Xcode project file generator.
+
+This module is both an Xcode project file generator and a documentation of the
+Xcode project file format.  Knowledge of the project file format was gained
+based on extensive experience with Xcode, and by making changes to projects in
+Xcode.app and observing the resultant changes in the associated project files.
+
+XCODE PROJECT FILES
+
+The generator targets the file format as written by Xcode 3.2 (specifically,
+3.2.6), but past experience has taught that the format has not changed
+significantly in the past several years, and future versions of Xcode are able
+to read older project files.
+
+Xcode project files are "bundled": the project "file" from an end-user's
+perspective is actually a directory with an ".xcodeproj" extension.  The
+project file from this module's perspective is actually a file inside this
+directory, always named "project.pbxproj".  This file contains a complete
+description of the project and is all that is needed to use the xcodeproj.
+Other files contained in the xcodeproj directory are simply used to store
+per-user settings, such as the state of various UI elements in the Xcode
+application.
+
+The project.pbxproj file is a property list, stored in a format almost
+identical to the NeXTstep property list format.  The file is able to carry
+Unicode data, and is encoded in UTF-8.  The root element in the property list
+is a dictionary that contains several properties of minimal interest, and two
+properties of immense interest.  The most important property is a dictionary
+named "objects".  The entire structure of the project is represented by the
+children of this property.  The objects dictionary is keyed by unique 96-bit
+values represented by 24 uppercase hexadecimal characters.  Each value in the
+objects dictionary is itself a dictionary, describing an individual object.
+
+Each object in the dictionary is a member of a class, which is identified by
+the "isa" property of each object.  A variety of classes are represented in a
+project file.  Objects can refer to other objects by ID, using the 24-character
+hexadecimal object key.  A project's objects form a tree, with a root object
+of class PBXProject at the root.  As an example, the PBXProject object serves
+as parent to an XCConfigurationList object defining the build configurations
+used in the project, a PBXGroup object serving as a container for all files
+referenced in the project, and a list of target objects, each of which defines
+a target in the project.  There are several different types of target object,
+such as PBXNativeTarget and PBXAggregateTarget.  In this module, this
+relationship is expressed by having each target type derive from an abstract
+base named XCTarget.
+
+The project.pbxproj file's root dictionary also contains a property, sibling to
+the "objects" dictionary, named "rootObject".  The value of rootObject is a
+24-character object key referring to the root PBXProject object in the
+objects dictionary.
+
+In Xcode, every file used as input to a target or produced as a final product
+of a target must appear somewhere in the hierarchy rooted at the PBXGroup
+object referenced by the PBXProject's mainGroup property.  A PBXGroup is
+generally represented as a folder in the Xcode application.  PBXGroups can
+contain other PBXGroups as well as PBXFileReferences, which are pointers to
+actual files.
+
+Each XCTarget contains a list of build phases, represented in this module by
+the abstract base XCBuildPhase.  Examples of concrete XCBuildPhase derivations
+are PBXSourcesBuildPhase and PBXFrameworksBuildPhase, which correspond to the
+"Compile Sources" and "Link Binary With Libraries" phases displayed in the
+Xcode application.  Files used as input to these phases (for example, source
+files in the former case and libraries and frameworks in the latter) are
+represented by PBXBuildFile objects, referenced by elements of "files" lists
+in XCTarget objects.  Each PBXBuildFile object refers to a PBXBuildFile
+object as a "weak" reference: it does not "own" the PBXBuildFile, which is
+owned by the root object's mainGroup or a descendant group.  In most cases, the
+layer of indirection between an XCBuildPhase and a PBXFileReference via a
+PBXBuildFile appears extraneous, but there's actually one reason for this:
+file-specific compiler flags are added to the PBXBuildFile object so as to
+allow a single file to be a member of multiple targets while having distinct
+compiler flags for each.  These flags can be modified in the Xcode applciation
+in the "Build" tab of a File Info window.
+
+When a project is open in the Xcode application, Xcode will rewrite it.  As
+such, this module is careful to adhere to the formatting used by Xcode, to
+avoid insignificant changes appearing in the file when it is used in the
+Xcode application.  This will keep version control repositories happy, and
+makes it possible to compare a project file used in Xcode to one generated by
+this module to determine if any significant changes were made in the
+application.
+
+Xcode has its own way of assigning 24-character identifiers to each object,
+which is not duplicated here.  Because the identifier only is only generated
+once, when an object is created, and is then left unchanged, there is no need
+to attempt to duplicate Xcode's behavior in this area.  The generator is free
+to select any identifier, even at random, to refer to the objects it creates,
+and Xcode will retain those identifiers and use them when subsequently
+rewriting the project file.  However, the generator would choose new random
+identifiers each time the project files are generated, leading to difficulties
+comparing "used" project files to "pristine" ones produced by this module,
+and causing the appearance of changes as every object identifier is changed
+when updated projects are checked in to a version control repository.  To
+mitigate this problem, this module chooses identifiers in a more deterministic
+way, by hashing a description of each object as well as its parent and ancestor
+objects.  This strategy should result in minimal "shift" in IDs as successive
+generations of project files are produced.
+
+THIS MODULE
+
+This module introduces several classes, all derived from the XCObject class.
+Nearly all of the "brains" are built into the XCObject class, which understands
+how to create and modify objects, maintain the proper tree structure, compute
+identifiers, and print objects.  For the most part, classes derived from
+XCObject need only provide a _schema class object, a dictionary that
+expresses what properties objects of the class may contain.
+
+Given this structure, it's possible to build a minimal project file by creating
+objects of the appropriate types and making the proper connections:
+
+  config_list = XCConfigurationList()
+  group = PBXGroup()
+  project = PBXProject({'buildConfigurationList': config_list,
+                        'mainGroup': group})
+
+With the project object set up, it can be added to an XCProjectFile object.
+XCProjectFile is a pseudo-class in the sense that it is a concrete XCObject
+subclass that does not actually correspond to a class type found in a project
+file.  Rather, it is used to represent the project file's root dictionary.
+Printing an XCProjectFile will print the entire project file, including the
+full "objects" dictionary.
+
+  project_file = XCProjectFile({'rootObject': project})
+  project_file.ComputeIDs()
+  project_file.Print()
+
+Xcode project files are always encoded in UTF-8.  This module will accept
+strings of either the str class or the unicode class.  Strings of class str
+are assumed to already be encoded in UTF-8.  Obviously, if you're just using
+ASCII, you won't encounter difficulties because ASCII is a UTF-8 subset.
+Strings of class unicode are handled properly and encoded in UTF-8 when
+a project file is output.

+             is_strong: If property_type is an XCObject subclass, is_strong
+                        is True to assert that this class "owns," or serves
+                        as parent, to the property value (or, if is_list is

+                          being set for the property.
+             default: Optional.  If is_requried is True, default may be set
+                      to provide a default value for objects that do not supply

+                      is not provided, users of the class must supply their own
+                      value for the property.
+             Note that although the values of the array are expressed in
+             boolean terms, subclasses provide values as integers to conserve
+             horizontal space.
+    _should_print_single_line: False in XCObject.  Subclasses whose objects
+                               should be written to the project file in the
+                               alternate single-line format, such as

+                        The index into this list is the ordinal of the
+                        character to transform; each value is a string
+                        used to represent the character in the output.  XCObject

+    _alternate_encode_transforms: Provided for subclasses that wish to use
+                                  the alternate encoding rules.  Xcode seems
+                                  to use these rules when printing objects in
+                                  single-line format.  Subclasses that desire
+                                  this behavior should set _encode_transforms
+                                  to _alternate_encode_transforms.
+    _hashables: A list of XCObject subclasses that can be hashed by ComputeIDs
+                to construct this object's ID.  Most classes that need custom
+                hashing behavior should do it by overriding Hashables,

+                to _hashables.
+  Attributes:
+    id: The object's identifier, a 24-character uppercase hexadecimal string.
+        Usually, objects being created should not set id until the entire

+    Hashables adds a hashable for each object, which means that if
+    the hierarchical structure changes (possibly due to changes caused when
+    TakeOverOnlyChild runs and encounters slight changes in the hierarchy),
+    the hashes will change.  For example, if a project file initially contains

+    a/b.  If someone later adds a/f2 to the project file, a/b can no longer be
+    collapsed, and f1 winds up with parent b and grandparent a.  That would
+    be sufficient to change f1's hash.
+
+    To counteract this problem, hashables for all XCHierarchicalElements except
+    for the main group (which has neither a name nor a path) are taken to be
+    just the set of path components.  Because hashables are inherited from
+    parents, this provides assurance that a/b/f1 has the same set of hashables
+    whether its parent is b or a/b.
+
+    The main group is a special case.  As it is permitted to have no name or

+If you want to write an option parser, and have it be good, there are
+two ways to do it.  The Right Way, and the Wrong Way.
+
+The Wrong Way is to sit down and write an option parser.  We've all done
+that.
+
+The Right Way is to write some complex configurable program with so many
+options that you hit the limit of your frustration just trying to
+manage them all, and defer it with duct-tape solutions until you see
+exactly to the core of the problem, and finally snap and write an
+awesome option parser.
+
+If you want to write an option parser, don't write an option parser.
+Write a package manager, or a source control system, or a service
+restarter, or an operating system.  You probably won't end up with a
+good one of those, but if you don't give up, and you are relentless and
+diligent enough in your procrastination, you may just end up with a very
+nice option parser.
+
+## USAGE
+
+    // my-program.js
+    var nopt = require("nopt")
+      , Stream = require("stream").Stream
+      , path = require("path")
+      , knownOpts = { "foo" : [String, null]
+                    , "bar" : [Stream, Number]
+                    , "baz" : path
+                    , "bloo" : [ "big", "medium", "small" ]
+                    , "flag" : Boolean
+                    , "pick" : Boolean
+                    , "many1" : [String, Array]
+                    , "many2" : [path]
+                    }
+      , shortHands = { "foofoo" : ["--foo", "Mr. Foo"]
+                     , "b7" : ["--bar", "7"]
+                     , "m" : ["--bloo", "medium"]
+                     , "p" : ["--pick"]
+                     , "f" : ["--flag"]
+                     }
+                 // everything is optional.
+                 // knownOpts and shorthands default to {}
+                 // arg list defaults to process.argv
+                 // slice defaults to 2
+      , parsed = nopt(knownOpts, shortHands, process.argv, 2)
+    console.log(parsed)
+
+This would give you support for any of the following:
+
+```bash
+$ node my-program.js --foo "blerp" --no-flag
+{ "foo" : "blerp", "flag" : false }
+
+$ node my-program.js ---bar 7 --foo "Mr. Hand" --flag
+{ bar: 7, foo: "Mr. Hand", flag: true }
+
+$ node my-program.js --foo "blerp" -f -----p
+{ foo: "blerp", flag: true, pick: true }
+
+$ node my-program.js -fp --foofoo
+{ foo: "Mr. Foo", flag: true, pick: true }
+
+$ node my-program.js --foofoo -- -fp  # -- stops the flag parsing.
+{ foo: "Mr. Foo", argv: { remain: ["-fp"] } }
+
+$ node my-program.js --blatzk -fp # unknown opts are ok.
+{ blatzk: true, flag: true, pick: true }
+
+$ node my-program.js --blatzk=1000 -fp # but you need to use = if they have a value
+{ blatzk: 1000, flag: true, pick: true }
+
+$ node my-program.js --no-blatzk -fp # unless they start with "no-"
+{ blatzk: false, flag: true, pick: true }
+
+$ node my-program.js --baz b/a/z # known paths are resolved.
+{ baz: "/Users/isaacs/b/a/z" }
+
+# if Array is one of the types, then it can take many
+# values, and will always be an array.  The other types provided
+# specify what types are allowed in the list.
+
+$ node my-program.js --many1 5 --many1 null --many1 foo
+{ many1: ["5", "null", "foo"] }
+
+$ node my-program.js --many2 foo --many2 bar
+{ many2: ["/path/to/foo", "path/to/bar"] }
+```
+
+Read the tests at the bottom of `lib/nopt.js` for more examples of
+what this puppy can do.
+
+## Types
+
+The following types are supported, and defined on `nopt.typeDefs`
+
+* String: A normal string.  No parsing is done.
+* path: A file system path.  Gets resolved against cwd if not absolute.
+* url: A url.  If it doesn't parse, it isn't accepted.
+* Number: Must be numeric.
+* Date: Must parse as a date. If it does, and `Date` is one of the options,
+  then it will return a Date object, not a string.
+* Boolean: Must be either `true` or `false`.  If an option is a boolean,
+  then it does not need a value, and its presence will imply `true` as
+  the value.  To negate boolean flags, do `--no-whatever` or `--whatever
+  false`
+* NaN: Means that the option is strictly not allowed.  Any value will
+  fail.
+* Stream: An object matching the "Stream" class in node.  Valuable
+  for use when validating programmatically.  (npm uses this to let you
+  supply any WriteStream on the `outfd` and `logfd` config options.)
+* Array: If `Array` is specified as one of the types, then the value
+  will be parsed as a list of options.  This means that multiple values
+  can be specified, and that the value will always be an array.
+
+If a type is an array of values not on this list, then those are
+considered valid values.  For instance, in the example above, the
+`--bloo` option can only be one of `"big"`, `"medium"`, or `"small"`,
+and any other value will be rejected.
+
+When parsing unknown fields, `"true"`, `"false"`, and `"null"` will be
+interpreted as their JavaScript equivalents.
+
+You can also mix types and values, or multiple types, in a list.  For
+instance `{ blah: [Number, null] }` would allow a value to be set to
+either a Number or null.  When types are ordered, this implies a
+preference, and the first type that can be used to properly interpret
+the value will be used.
+
+To define a new type, add it to `nopt.typeDefs`.  Each item in that
+hash is an object with a `type` member and a `validate` method.  The
+`type` member is an object that matches what goes in the type list.  The
+`validate` method is a function that gets called with `validate(data,
+key, val)`.  Validate methods should assign `data[key]` to the valid
+value of `val` if it can be handled properly, or return boolean
+`false` if it cannot.
+
+You can also call `nopt.clean(data, types, typeDefs)` to clean up a
+config object and remove its invalid properties.
+
+## Error Handling
+
+By default, nopt outputs a warning to standard error when invalid values for
+known options are found.  You can change this behavior by assigning a method
+to `nopt.invalidHandler`.  This method will be called with
+the offending `nopt.invalidHandler(key, val, types)`.
+
+If no `nopt.invalidHandler` is assigned, then it will console.error
+its whining.  If it is assigned to boolean `false` then the warning is
+suppressed.
+
+## Abbreviations
+
+Yes, they are supported.  If you define options like this:
+
+```javascript
+{ "foolhardyelephants" : Boolean
+, "pileofmonkeys" : Boolean }
+```
+
+Then this will work:
+
+```bash
+node program.js --foolhar --pil
+node program.js --no-f --pileofmon
+# etc.
+```
+
+## Shorthands
+
+Shorthands are a hash of shorter option names to a snippet of args that
+they expand to.
+
+If multiple one-character shorthands are all combined, and the
+combination does not unambiguously match any other option or shorthand,
+then they will be broken up into their constituent parts.  For example:
+
+```json
+{ "s" : ["--loglevel", "silent"]
+, "g" : "--global"
+, "f" : "--force"
+, "p" : "--parseable"
+, "l" : "--long"
+}
+```
+
+```bash
+npm ls -sgflp
+# just like doing this:
+npm ls --loglevel silent --global --force --long --parseable
+```
+
+## The Rest of the args
+
+The config object returned by nopt is given a special member called
+`argv`, which is an object with the following fields:
+
+* `remain`: The remaining args after all the parsing has occurred.
+* `original`: The args as they originally appeared.
+* `cooked`: The args after flags and shorthands are expanded.
+
+## Slicing
+
+Node programs are called with more or less the exact argv as it appears
+in C land, after the v8 and node-specific options have been plucked off.
+As such, `argv[0]` is always `node` and `argv[1]` is always the
+JavaScript program being run.
+
+That's usually not very useful to you.  So they're sliced off by
+default.  If you want them, then you can pass in `0` as the last
+argument, or any other number that you'd like to slice off the start of
+the list.

+
+The Artistic License 2.0
+
+Copyright (c) 2000-2006, The Perl Foundation.
+
+Everyone is permitted to copy and distribute verbatim copies
+of this license document, but changing it is not allowed.
+
+Preamble
+
+This license establishes the terms under which a given free software
+Package may be copied, modified, distributed, and/or redistributed.
+The intent is that the Copyright Holder maintains some artistic
+control over the development of that Package while still keeping the
+Package available as open source and free software.
+
+You are always permitted to make arrangements wholly outside of this
+license directly with the Copyright Holder of a given Package.  If the
+terms of this license do not permit the full use that you propose to
+make of the Package, you should contact the Copyright Holder and seek
+a different licensing arrangement.
+
+Definitions
+
+    "Copyright Holder" means the individual(s) or organization(s)
+    named in the copyright notice for the entire Package.
+
+    "Contributor" means any party that has contributed code or other
+    material to the Package, in accordance with the Copyright Holder's
+    procedures.
+
+    "You" and "your" means any person who would like to copy,
+    distribute, or modify the Package.
+
+    "Package" means the collection of files distributed by the
+    Copyright Holder, and derivatives of that collection and/or of
+    those files. A given Package may consist of either the Standard
+    Version, or a Modified Version.
+
+    "Distribute" means providing a copy of the Package or making it
+    accessible to anyone else, or in the case of a company or
+    organization, to others outside of your company or organization.
+
+    "Distributor Fee" means any fee that you charge for Distributing
+    this Package or providing support for this Package to another
+    party.  It does not mean licensing fees.
+
+    "Standard Version" refers to the Package if it has not been
+    modified, or has been modified only in ways explicitly requested
+    by the Copyright Holder.
+
+    "Modified Version" means the Package, if it has been changed, and
+    such changes were not explicitly requested by the Copyright
+    Holder.
+
+    "Original License" means this Artistic License as Distributed with
+    the Standard Version of the Package, in its current version or as
+    it may be modified by The Perl Foundation in the future.
+
+    "Source" form means the source code, documentation source, and
+    configuration files for the Package.
+
+    "Compiled" form means the compiled bytecode, object code, binary,
+    or any other form resulting from mechanical transformation or
+    translation of the Source form.
+
+
+Permission for Use and Modification Without Distribution
+
+(1)  You are permitted to use the Standard Version and create and use
+Modified Versions for any purpose without restriction, provided that
+you do not Distribute the Modified Version.
+
+
+Permissions for Redistribution of the Standard Version
+
+(2)  You may Distribute verbatim copies of the Source form of the
+Standard Version of this Package in any medium without restriction,
+either gratis or for a Distributor Fee, provided that you duplicate
+all of the original copyright notices and associated disclaimers.  At
+your discretion, such verbatim copies may or may not include a
+Compiled form of the Package.
+
+(3)  You may apply any bug fixes, portability changes, and other
+modifications made available from the Copyright Holder.  The resulting
+Package will still be considered the Standard Version, and as such
+will be subject to the Original License.
+
+
+Distribution of Modified Versions of the Package as Source
+
+(4)  You may Distribute your Modified Version as Source (either gratis
+or for a Distributor Fee, and with or without a Compiled form of the
+Modified Version) provided that you clearly document how it differs
+from the Standard Version, including, but not limited to, documenting
+any non-standard features, executables, or modules, and provided that
+you do at least ONE of the following:
+
+    (a)  make the Modified Version available to the Copyright Holder
+    of the Standard Version, under the Original License, so that the
+    Copyright Holder may include your modifications in the Standard
+    Version.
+
+    (b)  ensure that installation of your Modified Version does not
+    prevent the user installing or running the Standard Version. In
+    addition, the Modified Version must bear a name that is different
+    from the name of the Standard Version.
+
+    (c)  allow anyone who receives a copy of the Modified Version to
+    make the Source form of the Modified Version available to others
+    under
+
+        (i)  the Original License or
+
+        (ii)  a license that permits the licensee to freely copy,
+        modify and redistribute the Modified Version using the same
+        licensing terms that apply to the copy that the licensee
+        received, and requires that the Source form of the Modified
+        Version, and of any works derived from it, be made freely
+        available in that license fees are prohibited but Distributor
+        Fees are allowed.
+
+
+Distribution of Compiled Forms of the Standard Version
+or Modified Versions without the Source
+
+(5)  You may Distribute Compiled forms of the Standard Version without
+the Source, provided that you include complete instructions on how to
+get the Source of the Standard Version.  Such instructions must be
+valid at the time of your distribution.  If these instructions, at any
+time while you are carrying out such distribution, become invalid, you
+must provide new instructions on demand or cease further distribution.
+If you provide valid instructions or cease distribution within thirty
+days after you become aware that the instructions are invalid, then
+you do not forfeit any of your rights under this license.
+
+(6)  You may Distribute a Modified Version in Compiled form without
+the Source, provided that you comply with Section 4 with respect to
+the Source of the Modified Version.
+
+
+Aggregating or Linking the Package
+
+(7)  You may aggregate the Package (either the Standard Version or
+Modified Version) with other packages and Distribute the resulting
+aggregation provided that you do not charge a licensing fee for the
+Package.  Distributor Fees are permitted, and licensing fees for other
+components in the aggregation are permitted. The terms of this license
+apply to the use and Distribution of the Standard or Modified Versions
+as included in the aggregation.
+
+(8) You are permitted to link Modified and Standard Versions with
+other works, to embed the Package in a larger work of your own, or to
+build stand-alone binary or bytecode versions of applications that
+include the Package, and Distribute the result without restriction,
+provided the result does not expose a direct interface to the Package.
+
+
+Items That are Not Considered Part of a Modified Version
+
+(9) Works (including, but not limited to, modules and scripts) that
+merely extend or make use of the Package, do not, by themselves, cause
+the Package to be a Modified Version.  In addition, such works are not
+considered parts of the Package itself, and are not subject to the
+terms of this license.
+
+
+General Provisions
+
+(10)  Any use, modification, and distribution of the Standard or
+Modified Versions is governed by this Artistic License. By using,
+modifying or distributing the Package, you accept this license. Do not
+use, modify, or distribute the Package, if you do not accept this
+license.
+
+(11)  If your Modified Version has been derived from a Modified
+Version made by someone other than you, you are nevertheless required
+to ensure that your Modified Version complies with the requirements of
+this license.
+
+(12)  This license does not grant you the right to use any trademark,
+service mark, tradename, or logo of the Copyright Holder.
+
+(13)  This license includes the non-exclusive, worldwide,
+free-of-charge patent license to make, have made, use, offer to sell,
+sell, import and otherwise transfer the Package with respect to any
+patent claims licensable by the Copyright Holder that are necessarily
+infringed by the Package. If you institute patent litigation
+(including a cross-claim or counterclaim) against any party alleging
+that the Package constitutes direct or contributory patent
+infringement, then this Artistic License to you shall terminate on the
+date that such litigation is filed.
+
+(14)  Disclaimer of Warranty:
+THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS
+IS' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. THE IMPLIED
+WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, OR
+NON-INFRINGEMENT ARE DISCLAIMED TO THE EXTENT PERMITTED BY YOUR LOCAL
+LAW. UNLESS REQUIRED BY LAW, NO COPYRIGHT HOLDER OR CONTRIBUTOR WILL
+BE LIABLE FOR ANY DIRECT, INDIRECT, INCIDENTAL, OR CONSEQUENTIAL
+DAMAGES ARISING IN ANY WAY OUT OF THE USE OF THE PACKAGE, EVEN IF
+ADVISED OF THE POSSIBILITY OF SUCH DAMAGE.

+semver(1) -- The semantic versioner for npm
+===========================================
+
+## Usage
+
+    $ npm install semver
+    $ node
+    var semver = require('semver')
+
+    semver.valid('1.2.3') // '1.2.3'
+    semver.valid('a.b.c') // null
+    semver.clean('  =v1.2.3   ') // '1.2.3'
+    semver.satisfies('1.2.3', '1.x || >=2.5.0 || 5.0.0 - 7.2.3') // true
+    semver.gt('1.2.3', '9.8.7') // false
+    semver.lt('1.2.3', '9.8.7') // true
+
+As a command-line utility:
+
+    $ semver -h
+
+    SemVer 5.1.0
+
+    A JavaScript implementation of the http://semver.org/ specification
+    Copyright Isaac Z. Schlueter
+
+    Usage: semver [options] <version> [<version> [...]]
+    Prints valid versions sorted by SemVer precedence
+
+    Options:
+    -r --range <range>
+            Print versions that match the specified range.
+
+    -i --increment [<level>]
+            Increment a version by the specified level.  Level can
+            be one of: major, minor, patch, premajor, preminor,
+            prepatch, or prerelease.  Default level is 'patch'.
+            Only one version may be specified.
+
+    --preid <identifier>
+            Identifier to be used to prefix premajor, preminor,
+            prepatch or prerelease version increments.
+
+    -l --loose
+            Interpret versions and ranges loosely
+
+    Program exits successfully if any valid version satisfies
+    all supplied ranges, and prints all satisfying versions.
+
+    If no satisfying versions are found, then exits failure.
+
+    Versions are printed in ascending order, so supplying
+    multiple versions to the utility will just sort them.
+
+## Versions
+
+A "version" is described by the `v2.0.0` specification found at
+<http://semver.org/>.
+
+A leading `"="` or `"v"` character is stripped off and ignored.
+
+## Ranges
+
+A `version range` is a set of `comparators` which specify versions
+that satisfy the range.
+
+A `comparator` is composed of an `operator` and a `version`.  The set
+of primitive `operators` is:
+
+* `<` Less than
+* `<=` Less than or equal to
+* `>` Greater than
+* `>=` Greater than or equal to
+* `=` Equal.  If no operator is specified, then equality is assumed,
+  so this operator is optional, but MAY be included.
+
+For example, the comparator `>=1.2.7` would match the versions
+`1.2.7`, `1.2.8`, `2.5.3`, and `1.3.9`, but not the versions `1.2.6`
+or `1.1.0`.
+
+Comparators can be joined by whitespace to form a `comparator set`,
+which is satisfied by the **intersection** of all of the comparators
+it includes.
+
+A range is composed of one or more comparator sets, joined by `||`.  A
+version matches a range if and only if every comparator in at least
+one of the `||`-separated comparator sets is satisfied by the version.
+
+For example, the range `>=1.2.7 <1.3.0` would match the versions
+`1.2.7`, `1.2.8`, and `1.2.99`, but not the versions `1.2.6`, `1.3.0`,
+or `1.1.0`.
+
+The range `1.2.7 || >=1.2.9 <2.0.0` would match the versions `1.2.7`,
+`1.2.9`, and `1.4.6`, but not the versions `1.2.8` or `2.0.0`.
+
+### Prerelease Tags
+
+If a version has a prerelease tag (for example, `1.2.3-alpha.3`) then
+it will only be allowed to satisfy comparator sets if at least one
+comparator with the same `[major, minor, patch]` tuple also has a
+prerelease tag.
+
+For example, the range `>1.2.3-alpha.3` would be allowed to match the
+version `1.2.3-alpha.7`, but it would *not* be satisfied by
+`3.4.5-alpha.9`, even though `3.4.5-alpha.9` is technically "greater
+than" `1.2.3-alpha.3` according to the SemVer sort rules.  The version
+range only accepts prerelease tags on the `1.2.3` version.  The
+version `3.4.5` *would* satisfy the range, because it does not have a
+prerelease flag, and `3.4.5` is greater than `1.2.3-alpha.7`.
+
+The purpose for this behavior is twofold.  First, prerelease versions
+frequently are updated very quickly, and contain many breaking changes
+that are (by the author's design) not yet fit for public consumption.
+Therefore, by default, they are excluded from range matching
+semantics.
+
+Second, a user who has opted into using a prerelease version has
+clearly indicated the intent to use *that specific* set of
+alpha/beta/rc versions.  By including a prerelease tag in the range,
+the user is indicating that they are aware of the risk.  However, it
+is still not appropriate to assume that they have opted into taking a
+similar risk on the *next* set of prerelease versions.
+
+#### Prerelease Identifiers
+
+The method `.inc` takes an additional `identifier` string argument that
+will append the value of the string as a prerelease identifier:
+
+```javascript
+> semver.inc('1.2.3', 'prerelease', 'beta')
+'1.2.4-beta.0'
+```
+
+command-line example:
+
+```shell
+$ semver 1.2.3 -i prerelease --preid beta
+1.2.4-beta.0
+```
+
+Which then can be used to increment further:
+
+```shell
+$ semver 1.2.4-beta.0 -i prerelease
+1.2.4-beta.1
+```
+
+### Advanced Range Syntax
+
+Advanced range syntax desugars to primitive comparators in
+deterministic ways.
+
+Advanced ranges may be combined in the same way as primitive
+comparators using white space or `||`.
+
+#### Hyphen Ranges `X.Y.Z - A.B.C`
+
+Specifies an inclusive set.
+
+* `1.2.3 - 2.3.4` := `>=1.2.3 <=2.3.4`
+
+If a partial version is provided as the first version in the inclusive
+range, then the missing pieces are replaced with zeroes.
+
+* `1.2 - 2.3.4` := `>=1.2.0 <=2.3.4`
+
+If a partial version is provided as the second version in the
+inclusive range, then all versions that start with the supplied parts
+of the tuple are accepted, but nothing that would be greater than the
+provided tuple parts.
+
+* `1.2.3 - 2.3` := `>=1.2.3 <2.4.0`
+* `1.2.3 - 2` := `>=1.2.3 <3.0.0`
+
+#### X-Ranges `1.2.x` `1.X` `1.2.*` `*`
+
+Any of `X`, `x`, or `*` may be used to "stand in" for one of the
+numeric values in the `[major, minor, patch]` tuple.
+
+* `*` := `>=0.0.0` (Any version satisfies)
+* `1.x` := `>=1.0.0 <2.0.0` (Matching major version)
+* `1.2.x` := `>=1.2.0 <1.3.0` (Matching major and minor versions)
+
+A partial version range is treated as an X-Range, so the special
+character is in fact optional.
+
+* `""` (empty string) := `*` := `>=0.0.0`
+* `1` := `1.x.x` := `>=1.0.0 <2.0.0`
+* `1.2` := `1.2.x` := `>=1.2.0 <1.3.0`
+
+#### Tilde Ranges `~1.2.3` `~1.2` `~1`
+
+Allows patch-level changes if a minor version is specified on the
+comparator.  Allows minor-level changes if not.
+
+* `~1.2.3` := `>=1.2.3 <1.(2+1).0` := `>=1.2.3 <1.3.0`
+* `~1.2` := `>=1.2.0 <1.(2+1).0` := `>=1.2.0 <1.3.0` (Same as `1.2.x`)
+* `~1` := `>=1.0.0 <(1+1).0.0` := `>=1.0.0 <2.0.0` (Same as `1.x`)
+* `~0.2.3` := `>=0.2.3 <0.(2+1).0` := `>=0.2.3 <0.3.0`
+* `~0.2` := `>=0.2.0 <0.(2+1).0` := `>=0.2.0 <0.3.0` (Same as `0.2.x`)
+* `~0` := `>=0.0.0 <(0+1).0.0` := `>=0.0.0 <1.0.0` (Same as `0.x`)
+* `~1.2.3-beta.2` := `>=1.2.3-beta.2 <1.3.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+
+#### Caret Ranges `^1.2.3` `^0.2.5` `^0.0.4`
+
+Allows changes that do not modify the left-most non-zero digit in the
+`[major, minor, patch]` tuple.  In other words, this allows patch and
+minor updates for versions `1.0.0` and above, patch updates for
+versions `0.X >=0.1.0`, and *no* updates for versions `0.0.X`.
+
+Many authors treat a `0.x` version as if the `x` were the major
+"breaking-change" indicator.
+
+Caret ranges are ideal when an author may make breaking changes
+between `0.2.4` and `0.3.0` releases, which is a common practice.
+However, it presumes that there will *not* be breaking changes between
+`0.2.4` and `0.2.5`.  It allows for changes that are presumed to be
+additive (but non-breaking), according to commonly observed practices.
+
+* `^1.2.3` := `>=1.2.3 <2.0.0`
+* `^0.2.3` := `>=0.2.3 <0.3.0`
+* `^0.0.3` := `>=0.0.3 <0.0.4`
+* `^1.2.3-beta.2` := `>=1.2.3-beta.2 <2.0.0` Note that prereleases in
+  the `1.2.3` version will be allowed, if they are greater than or
+  equal to `beta.2`.  So, `1.2.3-beta.4` would be allowed, but
+  `1.2.4-beta.2` would not, because it is a prerelease of a
+  different `[major, minor, patch]` tuple.
+* `^0.0.3-beta` := `>=0.0.3-beta <0.0.4`  Note that prereleases in the
+  `0.0.3` version *only* will be allowed, if they are greater than or
+  equal to `beta`.  So, `0.0.3-pr.2` would be allowed.
+
+When parsing caret ranges, a missing `patch` value desugars to the
+number `0`, but will allow flexibility within that value, even if the
+major and minor versions are both `0`.
+
+* `^1.2.x` := `>=1.2.0 <2.0.0`
+* `^0.0.x` := `>=0.0.0 <0.1.0`
+* `^0.0` := `>=0.0.0 <0.1.0`
+
+A missing `minor` and `patch` values will desugar to zero, but also
+allow flexibility within those values, even if the major version is
+zero.
+
+* `^1.x` := `>=1.0.0 <2.0.0`
+* `^0.x` := `>=0.0.0 <1.0.0`
+
+### Range Grammar
+
+Putting all this together, here is a Backus-Naur grammar for ranges,
+for the benefit of parser authors:
+
+```bnf
+range-set  ::= range ( logical-or range ) *
+logical-or ::= ( ' ' ) * '||' ( ' ' ) *
+range      ::= hyphen | simple ( ' ' simple ) * | ''
+hyphen     ::= partial ' - ' partial
+simple     ::= primitive | partial | tilde | caret
+primitive  ::= ( '<' | '>' | '>=' | '<=' | '=' | ) partial
+partial    ::= xr ( '.' xr ( '.' xr qualifier ? )? )?
+xr         ::= 'x' | 'X' | '*' | nr
+nr         ::= '0' | ['1'-'9'] ( ['0'-'9'] ) *
+tilde      ::= '~' partial
+caret      ::= '^' partial
+qualifier  ::= ( '-' pre )? ( '+' build )?
+pre        ::= parts
+build      ::= parts
+parts      ::= part ( '.' part ) *
+part       ::= nr | [-0-9A-Za-z]+
+```
+
+## Functions
+
+All methods and classes take a final `loose` boolean argument that, if
+true, will be more forgiving about not-quite-valid semver strings.
+The resulting output will always be 100% strict, of course.
+
+Strict-mode Comparators and Ranges will be strict about the SemVer
+strings that they parse.
+
+* `valid(v)`: Return the parsed version, or null if it's not valid.
+* `inc(v, release)`: Return the version incremented by the release
+  type (`major`,   `premajor`, `minor`, `preminor`, `patch`,
+  `prepatch`, or `prerelease`), or null if it's not valid
+  * `premajor` in one call will bump the version up to the next major
+    version and down to a prerelease of that major version.
+    `preminor`, and `prepatch` work the same way.
+  * If called from a non-prerelease version, the `prerelease` will work the
+    same as `prepatch`. It increments the patch version, then makes a
+    prerelease. If the input version is already a prerelease it simply
+    increments it.
+* `prerelease(v)`: Returns an array of prerelease components, or null
+  if none exist. Example: `prerelease('1.2.3-alpha.1') -> ['alpha', 1]`
+* `major(v)`: Return the major version number.
+* `minor(v)`: Return the minor version number.
+* `patch(v)`: Return the patch version number.
+
+### Comparison
+
+* `gt(v1, v2)`: `v1 > v2`
+* `gte(v1, v2)`: `v1 >= v2`
+* `lt(v1, v2)`: `v1 < v2`
+* `lte(v1, v2)`: `v1 <= v2`
+* `eq(v1, v2)`: `v1 == v2` This is true if they're logically equivalent,
+  even if they're not the exact same string.  You already know how to
+  compare strings.
+* `neq(v1, v2)`: `v1 != v2` The opposite of `eq`.
+* `cmp(v1, comparator, v2)`: Pass in a comparison string, and it'll call
+  the corresponding function above.  `"==="` and `"!=="` do simple
+  string comparison, but are included for completeness.  Throws if an
+  invalid comparison string is provided.
+* `compare(v1, v2)`: Return `0` if `v1 == v2`, or `1` if `v1` is greater, or `-1` if
+  `v2` is greater.  Sorts in ascending order if passed to `Array.sort()`.
+* `rcompare(v1, v2)`: The reverse of compare.  Sorts an array of versions
+  in descending order when passed to `Array.sort()`.
+* `diff(v1, v2)`: Returns difference between two versions by the release type
+  (`major`, `premajor`, `minor`, `preminor`, `patch`, `prepatch`, or `prerelease`),
+  or null if the versions are the same.
+
+
+### Ranges
+
+* `validRange(range)`: Return the valid range or null if it's not valid
+* `satisfies(version, range)`: Return true if the version satisfies the
+  range.
+* `maxSatisfying(versions, range)`: Return the highest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `minSatisfying(versions, range)`: Return the lowest version in the list
+  that satisfies the range, or `null` if none of them do.
+* `gtr(version, range)`: Return `true` if version is greater than all the
+  versions possible in the range.
+* `ltr(version, range)`: Return `true` if version is less than all the
+  versions possible in the range.
+* `outside(version, range, hilo)`: Return true if the version is outside
+  the bounds of the range in either the high or low direction.  The
+  `hilo` argument must be either the string `'>'` or `'<'`.  (This is
+  the function called by `gtr` and `ltr`.)
+
+Note that, since ranges may be non-contiguous, a version might not be
+greater than a range, less than a range, *or* satisfy a range!  For
+example, the range `1.2 <1.2.9 || >2.0.0` would have a hole from `1.2.9`
+until `2.0.0`, so the version `1.2.10` would not be greater than the
+range (because `2.0.1` satisfies, which is higher), nor less than the
+range (since `1.2.8` satisfies, which is lower), and it also does not
+satisfy the range.
+
+If you want to know if a version satisfies or does not satisfy a
+range, use the `satisfies(version, range)` function.

-Configuration
---------
-
-__`node-gyp` responds to environment variables or `npm` configuration__
-1. Environment variables take the form `npm_config_OPTION_NAME` for any of the 
- options listed above (dashes in option names should be replaced by underscores).
- These work also when `node-gyp` is invoked directly:  
- `$ export npm_config_devdir=/tmp/.gyp`  
- or on Windows  
- `> set npm_config_devdir=c:\temp\.gyp`  
-2. As `npm` configuration, variables take the form `OPTION_NAME`.
- This way only works when `node-gyp` is executed by `npm`:  
- `$ npm config set [--global] devdir /tmp/.gyp`  
- `$ npm i buffertools`

+
+### Environment variables
+
+Use the form `npm_config_OPTION_NAME` for any of the command options listed
+above (dashes in option names should be replaced by underscores).
+
+For example, to set `devdir` equal to `/tmp/.gyp`, you would:
+
+Run this on Unix:
+
+```bash
+$ export npm_config_devdir=/tmp/.gyp
+```
+
+Or this on Windows:
+
+```console
+> set npm_config_devdir=c:\temp\.gyp
+```
+
+### `npm` configuration
+
+Use the form `OPTION_NAME` for any of the command options listed above.
+
+For example, to set `devdir` equal to `/tmp/.gyp`, you would run:
+
+```bash
+$ npm config set [--global] devdir /tmp/.gyp
+```
+
+**Note:** Configuration set via `npm` will only be used when `node-gyp`
+is run via `npm`, not when `node-gyp` is run directly.

-# node-tar
-
-Tar for Node.js.
-
-[![NPM](https://nodei.co/npm/tar.png)](https://nodei.co/npm/tar/)
-
-## API
-
-See `examples/` for usage examples.
-
-### var tar = require('tar')
-
-Returns an object with `.Pack`, `.Extract` and `.Parse` methods.
-
-### tar.Pack([properties])
-
-Returns a through stream. Use
-[fstream](https://npmjs.org/package/fstream) to write files into the
-pack stream and you will receive tar archive data from the pack
-stream.
-
-This only works with directories, it does not work with individual files.
-
-The optional `properties` object are used to set properties in the tar
-'Global Extended Header'. If the `fromBase` property is set to true,
-the tar will contain files relative to the path passed, and not with
-the path included.
-
-### tar.Extract([options])
-
-Returns a through stream. Write tar data to the stream and the files
-in the tarball will be extracted onto the filesystem.
-
-`options` can be:
-
-```js
-{
-  path: '/path/to/extract/tar/into',
-  strip: 0, // how many path segments to strip from the root when extracting
-}
-```
-
-`options` also get passed to the `fstream.Writer` instance that `tar`
-uses internally.
-
-### tar.Parse()
-
-Returns a writable stream. Write tar data to it and it will emit
-`entry` events for each entry parsed from the tarball. This is used by
-`tar.Extract`.
