ABOUT CHIPMUNK:
  Chipmunk is a simple, lightweight and fast 2D rigid body physics library
  written in C by Slembcke. It's licensed under the unrestrictive, OSI approved
  MIT license.

ABOUT THESE RUBY BINDINGS:
  Although chipmunk comes with ruby bindings, they are not always up to date
  with regards to the functionality of the C library, and historically, they
  have been incompatible with recent versions of Ruby.

  Therefore, these bindings are intended to as an enhanced version with more
  features and better compatibility with recent versions of Ruby. They are also
  intended to be an alternative to the chipmunk-ffi bindings when performance
  is of the utmost importance, as it may be for games.

  The intent is for these bindings to be mostly source code compatible with the
  FFI bindings. Main exceptions are when it did not support the functionality I
  added yet. All this is documented by specs and by the html documentation.

  If you have any problems with these bindings, please contact the maintainer at
  shawn42@gmail.com, or report the issue on the issue tracker:
  https://github.com/chipmunk-rb/chipmunk/issues

REQUIREMENTS
  * 1.9.x.
  * rspec for running the specs.
  * rake and rake-compiler for compiling the extension.


INSTALLATION
  Clone this repository and do:

  rake clean compile

  There is also a gem available for Linux and OS/X, and a binary gem for Windows,
  which you can try to install with:

  gem install chipmunk

  However, due to incompatilties in the latest versions of
  Rake, Rake-Compiler and rubygems, the gem method of installation may fail for
  you. This will be solved when these incompatibilities are solved by these
  upstream tools.

  These bindings vendor Chipmunk 6.1.3 with a few extra patches, so you don't
  need to have it installed.

DOCUMENTATION:
  Full handcrafted documentation based on the C documentation is available at:
  http://chipmunk-rb.github.com/chipmunk/

CHANGES:
  * Bumped to Chipmunk version 6.1.3; dropped 1.8 support
  * Since 5.3.4.4: Vendored chipmunk again, uncleanly. should compile well now.
  * Version 5.3.4.2 and 5.3.4.3 are broken, don't use them.
  * Since 5.3.4.1: Vendored chipmunk again, cleanly. Several bugfixes.
  * Since 5.1.0  : Much more of Chipmunk's functionality is wrapped. Unvendored
    chipmunk. More specs and documentation.

VERSIONING POLICY:
  Since 6.1.3.0 these bindings follow the version of chipmunk, followed by an
  extra number for the version of the bindings. All major releases will be
  backwards compatible in their API. The API may be enhanced in minor releases.

KNOWN BUGS:
  * There are no bindings to SpaceHash since I think they are not so useful
    anymore since Chipmunk supports BB queries.
  * Some methods may crash with a segentation violation in case they are not
    used correctly, according to the underlying requirements of the C library.

CONTRACTING:
  Howling Moon Software (Slembke's company) is available for contracting if you
  want to make the physics in your game really stand out. Feel free to contact
  them through their webpage: http://howlingmoonsoftware.com/contracting.php

TODO:
  * Allow several constructors to be more flexible and take nil as a default
    argument.
  * Try to prevent segfauts on incorrect use of certain methods, if possible.
  * Some more specs.
  * Fix the gem when the upstream tools get fixed.

INFO FOR MAINTAINERS:

(1) 1/10/09 Cross-Platform Gem built by John Mair (banisterfiend)
