-"Eggsecutable" Scripts
-----------------------
-
-Occasionally, there are situations where it's desirable to make an ``.egg``
-file directly executable.  You can do this by including an entry point such
-as the following::
-
-    setup(
-        # other arguments here...
-        entry_points={
-            'setuptools.installation': [
-                'eggsecutable = my_package.some_module:main_func',
-            ]
-        }
-    )
-
-Any eggs built from the above setup script will include a short executable
-prelude that imports and calls ``main_func()`` from ``my_package.some_module``.
-The prelude can be run on Unix-like platforms (including Mac and Linux) by
-invoking the egg with ``/bin/sh``, or by enabling execute permissions on the
-``.egg`` file.  For the executable prelude to run, the appropriate version of
-Python must be available via the ``PATH`` environment variable, under its
-"long" name.  That is, if the egg is built for Python 2.3, there must be a
-``python2.3`` executable present in a directory on ``PATH``.
-
-This feature is primarily intended to support ez_setup the installation of
-setuptools itself on non-Windows platforms, but may also be useful for other
-projects as well.
-
-IMPORTANT NOTE: Eggs with an "eggsecutable" header cannot be renamed, or
-invoked via symlinks.  They *must* be invoked using their original filename, in
-order to ensure that, once running, ``pkg_resources`` will know what project
-and version is in use.  The header script will check this and exit with an
-error if the ``.egg`` file has been renamed or is invoked via a symlink that
-changes its base name.
