# Slackware SlackBuild script 
# ===========================
# By:        Eric Hameleers <alien@slackware.com>
# For:       dvdrtools
# Descr:     a fork of cdrtools adding support for dvd media
# URL:       http://www.arklinux.org/projects/dvdrtools/
# Needs:     
# Remarks:   This package was _not_ compiled against transcode. This means that
#            the Video DVD mastering tools were not built. If you do want them,
#            install a transcode package and re-build the package using this
#            SlackBuild script (no changes to the script needed).
# Changelog:
# 0.3.1-1:   05/aug/2006 by Eric Hameleers <alien@slackware.com>
#            * Initial build (with parts copied from cdrtools.SlackBuild
#              by Patrick Volkerding).
# 
# Run 'sh SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'.
