Update of /cvsroot/freevo/freevo/src/input/plugins
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv17121
Added Files:
event_device.py
Log Message:
A linux event input device plugin, still a work in progress but I am using
this for my PVR-250 remote with a custom keymap. You may find some input
tools to modify the keymap at
http://dl.bytesex.org/cvs-snapshots/input-20040421-115547.tar.gz .
I will incorporate the keymap viewing & loading tool into a freevo helper
program. plugin.activate('input.event_device')

# Event input device support. A work in progress / proof of concept. With this
# we can totally bypass lirc if there's an event input driver for a given
