# @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.
