- """
- Creates a bootstrap script, which is like this script but with
- extend_parser, adjust_options, and after_install hooks.
- This returns a string that (written to disk of course) can be used
- as a bootstrap script with your own customizations. The script
- will be the standard virtualenv.py script, with your extra text
- added (your extra text should be Python code).
- 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.
