 # GStreamer Plug-ins splitup
 
+*Note :* The GStreamer plugins were split-up starting from GStreamer 0.10.
+
 Here is some explanation regarding the split-up of plug-ins into separate
 modules. Without further ado ...

 GStreamer Plugins has grown so big that it's hard to separate the wheat from
 the chaff. Also, distributors have brought up issues about the legal status
 of some of the plug-ins we ship. To remedy this, we've divided the previous
 set of available plug-ins into four modules:
 
+
 ### gst-plugins-base
 
-a small and fixed set of plug-ins, covering a wide range
-of possible types of elements; these are continuously kept up-to-date
-with any core changes during the development series.

+the development series.
+
 * We believe distributors can safely ship these plug-ins
 * People writing elements should base their code on these elements
 * These elements come with examples, documentation, and regression tests
 
+
 ### gst-plugins-good
 
-a set of plug-ins that we consider to have good quality
-code, correct functionality, our preferred license (LGPL for the plug-in
-code, LGPL or LGPL-compatible for the supporting library).

-a set of plug-ins that have good quality and correct
-functionality, but distributing them might pose problems. The license
-on either the plug-ins or the supporting libraries might not be how we'd
-like. The code might be widely known to present patent problems.

-a set of plug-ins that aren't up to par compared to the
-rest. They might be close to being good quality, but they're missing
-something - be it a good code review, some documentation, a set of tests,
-a real live maintainer, or some actual wide use.
