If you include these functions, they will be called: ``extend_parser(optparse_parser)``: You can add or remove options from the parser here. ``adjust_options(options, args)``: You can change options here, or change the args (if you accept different kinds of arguments, be sure you modify ``args`` so it is only ``[DEST_DIR]``). ``after_install(options, home_dir)``: After everything is installed, this function is called. This is probably the function you are most likely to use. An example would be:: def after_install(options, home_dir): subprocess.call([join(home_dir, 'bin', 'easy_install'), 'MyPackage']) subprocess.call([join(home_dir, 'bin', 'my-package-script'), 'setup', home_dir]) This example immediately installs a package, and runs a setup script from that package. If you provide something like ``python_version='2.5'`` then the script will start with ``#!/usr/bin/env python2.5`` instead of ``#!/usr/bin/env python``. You can use this when the script must be run with a particular Python version.
