| Creates a bootstrap script, which is like this script but with |

| |
| 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]``). |

| |
| 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 |
