 """Parse a DEPS file and git checkout all of the dependencies.
 
 Args:
   An optional list of deps_os values.
 
 Environment Variables:
-  GIT_EXECUTABLE: path to "git" binary; if unset, will look for one of
-  ['git', 'git.exe', 'git.bat'] in your default path.
-
   GIT_SYNC_DEPS_PATH: file to get the dependency list from; if unset,
   will use the file ../DEPS relative to this script's directory.
 
   GIT_SYNC_DEPS_QUIET: if set to non-empty string, suppress messages.
 
 Git Config:
   To disable syncing of a single repository:
       cd path/to/repository
       git config sync-deps.disable true
 
   To re-enable sync:
       cd path/to/repository
       git config --unset sync-deps.disable
