13 # @BLURB: Manages build for invididual ebuild for gst-plugins.
14 # @DESCRIPTION:
15 # Eclass to make external gst-plugins emergable on a per-plugin basis and
16 # to solve the problem with gst-plugins generating far too much unneeded
17 # dependancies.
18 #
19 # GStreamer consuming applications should depend on the specific plugins they
20 # need as defined in their source code.
21 #
22 # In case of spider usage, obtain recommended plugins to use from Gentoo
23 # developers responsible for gstreamer <gstreamer@gentoo.org> or the application
24 # developer.
