-.SYNOPSIS
-Run this PowerShell script to enable dev mode and/or a custom script for the TypeScript language service, e.g.
-
-PS C:\> .\scripts\VSDevMode.ps1 -enableDevMode -tsScript C:\src\TypeScript\built\local\
-
-Note: If you get security errors, try running powershell as an Administrator and with the "-executionPolicy remoteSigned" switch
-
-.PARAMETER vsVersion
-Set to "12" for Dev12 (VS2013) or "14" (the default) for Dev14 (VS2015)
-
-.PARAMETER enableDevMode
-Pass this switch to enable attaching a debugger to the language service
-
-.PARAMETER tsScript
-The path to a directory containing a custom language service script to use (typescriptServices.js), e.g. "C:\src\TypeScript\built\local\"

-/** Run via:

- */
-
-// This script does two things: 
-//  
-//  - Listens to changes to the built version of TypeScript (via a filewatcher on `built/local/typescriptServices.js`)
-//    these trigger creating monaco-typescript compatible builds of TypeScript at `internal/lib/typescriptServices.js§
-//
-//  - Creates a HTTP server which the playground uses. The webserver almost exclusively re-directs requests to 
-//    the latest stable version of monaco-typescript, but specifically overrides requests for the TypeScript js
-//    file to the version created in the above step.
-//
