BRANCH_PLUGINS branch!
Authors:
Bryce Denney
Christophe Bothamy
Kevin Lawton (we grabbed a lot of plugin code from plex86)
Testing help from:
Volker Ruppert
Don Becker (Psyon)
Jeremy Parsons (Br'fin)
The change log is too long to paste in here. To read the change log, do
cvs log patches/patch.final-from-BRANCH_PLUGINS.gz
All the changes and a detailed description are contained in a patch
called patch.final-from-BRANCH_PLUGINS.gz. To look at the complete
patch, do
cvs upd -r1.1 patches/patch.final-from-BRANCH_PLUGINS.gz
Then you will have a local copy of the patch, which you can gunzip and
play with however you want.
