#             * Update.
# 
# Run 'sh mplayer-codecs.SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'. 
#
# -----------------------------------------------------------------------------

# Set initial variables:

# Set TYPE=${TYPE:-"all"} if you want the "all"-codecs package built by default.
# Usually, "essential" would be sufficient for MPlayer, but you might need
# "all" for xine.
