# This script will:
#  1) download the sources needed to build libdvdcss2 RPM
#  2) Ask the root password
#  3) Build the binary RPM packages and install it.
#     NOTE: To build is needed to install before the following packages:
#       gcc       (the C GNU compiler)
#       make      (the make build GNU utility)
#       wget      (the tool to download the source code)
#  To use it, you will need an internet conection up to download the sources
#    a) Download the script
#    b) move it to a temp directory
#    c) cd to that temp directory
#    d) execute the script (you will need to know the root password and the
#        internet conection up)
#       ./install_libdvdcss2
