# 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 DEBIAN GNU/Linux
