# Freevo distutils for installing plug-ins
# -----------------------------------------------------------------------
# $Id: distutils.py 10563 2008-03-22 22:31:35Z duncan $
#
# Notes:
#  If you want to create a package with a plug-in, you have to rebuild
#  the freevo directory structure. E.g. if you have a video plug-in and
#  an image for it, you should have the following structure:
#
#  root
#    |--> setup.py
#    |
#    |--> share
#    | |--> images
#    | | |--> file.jpg
#    |
#    |--> src
#    | |--> video
#    | | |--> plugins
#    | | | |--> __init__.py (empty)
#    | | | |--> plugin.py
#
#
#  The setup.py file should look like this:
#
#  |   #!/usr/bin/env python2
#  |
#  |   """Setup script for my freevo plug-in."""
#  |
#  |
#  |   __revision__ = "$Id: distutils.py 10563 2008-03-22 22:31:35Z duncan $"
#  |
#  |   from distutils.core import setup, Extension
#  |   import distutils.command.install
#  |   from freevo.util.distutils import *
#  |
#  |   # now start the python magic
#  |   setup (name = "nice_plugin",
#  |          version = '0.1',
#  |          description = "My first plug-in",
#  |          author = "me",
#  |          author_email = "my@mail.address",
#  |          url = "http://i-also-have-a-web.address",
#  |
#  |          package_dir = package_dir,
#  |          packages    = packages,
#  |          data_files  = data_files
#  |          )
#  |   finalize()
#
#
#  To auto-build distribution packages, a MANIFEST.in is helpful. You should
#  create one, e.g.
#
#  |   recursive-include src *.py
#  |   recursive-include share *
#  |   include *
