Cloning this repository

When cloning this repository please pass the --recursive flag to git:

git clone --recursive [URL]

This will properly install the WebGLDeveloperTools repository as a git submodule under sdk/devtools/.

The last edited date in several specifications is automatically updated via a smudge filter. To benefit from this you must issue the following commands in the root of your clone.

On Unix (Linux, Mac OS X, etc.) platforms and Windows using Git for Windows' Git Bash or Cygwin's bash terminal:

rm specs/latest/*/index.html
git checkout !$

On Windows with the Command Prompt (requires git.exe in a directory on your %PATH%):

del specs/latest/1.0/index.html specs/latest/2.0/index.html 
git checkout specs/latest/1.0/index.html specs/latest/2.0/index.html 

The first command adds an [include] of the repo's .gitconfig to the local git config file.git/config in your clone of the repo. .gitconfig contains the config of the “dater” filter. The remaining commands force a new checkout of the index.html files to smudge them with the date. These two are unnecessary if you plan to edit these files. All are unecessary if you do not care about having the dates shown.
