# @DESCRIPTION:
# Eclass to make external gst-plugins emergable on a per-plugin basis
# and to solve the problem with gst-plugins generating far too much
# unneeded dependencies.
#
# GStreamer consuming applications should depend on the specific plugins
# they need as defined in their source code. Usually you can find that
# out by grepping the source tree for 'factory_make'. If it uses playbin
# plugin, consider adding media-plugins/gst-plugins-meta dependency, but
# also list any packages that provide explicitly requested plugins.
