# Original Author: Arun Raghavan <ford_prefect@gentoo.org> (based on the
#		   gnome-python-desktop eclass by Jim Ramsay <lack@gentoo.org>)
#
# Purpose: Provides common functionality required for building the gnome-python*
# 		   bindings
#
# Important environment variables:
#
# G_PY_PN: Which gnome-python* package bindings we're working with. Defaults to
#		   gnome-python if unset.
#
# G_PY_BINDINGS: The actual '--enable-<binding>' name, which by default is ${PN}
# 		   excluding the -python at the end. May be overridden if necessary.
#
# EXAMPLES: The set of example files to be installed if the 'examples' USE flag
# 		   is set.
#
# The naming convention for all bindings is as follows:
#	dev-python/<original-${PN}-for-which-this-is-the-binding>-python
#
# So, for example, with the bonobo bindings, the original package is libbonobo
# and the packages is named dev-python/libbonobo-python
