Sample programs callable through git-shell. Place a directory named 'git-shell-commands' in the home directory of a user whose shell is git-shell. Then anyone logging in as that user will be able to run executables in the 'git-shell-commands' directory. Provided commands: help: Prints out the names of available commands. When run interactively, git-shell will automatically run 'help' on startup, provided it exists. list: Displays any bare repository whose name ends with ".git" under user's home directory. No other git repositories are visible, although they might be clonable through git-shell. 'list' is designed to minimize the number of calls to git that must be made in finding available repositories; if your setup has additional repositories that should be user-discoverable, you may wish to modify 'list' accordingly.
