# gst-plugins-good eclass
#
# eclass to make external gst-plugins emergable on a per-plugin basis
# to solve the problem with gst-plugins generating far too much unneeded deps
#
# 3rd party applications using gstreamer now should depend on a set of plugins as
# defined in the source, obtain recommended plugins to use from
# Gentoo developers responsible for gstreamer <gnome@gentoo.org>, the application developer
# or the gstreamer team.
