# Shell script to install libdvdcss under Debian GNU Linux
# Many DVDs use css for encryption.  To play these discs, a special library 
# is needed to decode them, libdvdcss.  Due to legal problems, Debian and most
# Linux distibutions cannot distribute libdvdcss
# Use this shell script to install the libdvdcss under DEBIN GNU/Linux

# Script to logoff KDE/Gnome user session. 
# With proper permission via sudo it is possible that rest of the users 
# can use the same script. You can create Launcher to use this script 
# from Linux desktop. Tested on Debian Linux 3.x, but it should work with
# other Linux distros and FreeBSD
