The subcommand_driver automatically figures out what name the script was called as, then looks for subcommands and runs them if found, passing in any command line options.

If you have a `foo` script in your `$PATH` as shown below

#!/usr/bin/env python3 from gitlike_commands import subcommand_driver

if __name__ == '__main__': subcommand_driver()

Running `foo bar baz` will look for a `foo-bar-baz` script, and if present in your $PATH, run it. If there is no `foo-bar-baz`, it will look for `foo-bar`, and if it finds that, run `foo-bar baz`.

The subcommands can be written in any language, the only requirements are that they are marked executable and follow the `foo-something` naming convention.
