# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        handbrake
# Descr:      video transcoder and ripper
# URL:        http://handbrake.fr/
# Needs:      vlc or libdvdcss (to read encrypted DVD's)
# Changelog:  
# r2606-1:    23/Jun/2009 by Eric Hameleers, Eindhoven, NL
#             * Initial build.
#                Note, that handbrake will download a lot of other dependencies
#                on it's own, so it will require an Internet connection during
#                compilation.
# r2830-1:    20/sep/2009 by Eric Hameleers <alien@slackware.com>
#             * Update.
# 0.9.4-1:    26/nov/2009 by Eric Hameleers <alien@slackware.com>
#             * Stable release, first in a year!
# 0.9.4-2:    01/jun/2010 by Eric Hameleers <alien@slackware.com>
#             * Rebuild for Slackware 13.1; package can now be built without
#               an internet connection.
# 0.9.5-1:    04/jan/2011 by Eric Hameleers <alien@slackware.com>
#             * Finally, a new release. Also, make it show an icon in the
#               XFCE menu. This package no longer depends on webkitgtk.
# 0.9.6-1:    13/apr/2012 by Eric Hameleers <alien@slackware.com>
#             * New release.
# 0.9.8-1:    31/aug/2012 by Eric Hameleers <alien@slackware.com>
#             * New release.
# 0.9.9-1:    03/jun/2013 by Eric Hameleers <alien@slackware.com>
#             * New release.
# 0.10.2-1:   01/oct/2015 by Eric Hameleers <alien@slackware.com>
#             * New release, slackware-current only (GTK+3 requirements)
# 0.10.5-1:   03/apr/2016 by Eric Hameleers <alien@slackware.com>
#             * Update, slackware-current only (GTK+3 requirements)
# 
# Run 'sh handbrake.SlackBuild' to build a Slackware package.
# The package (.txz) and .txt file as well as build logs are created in /tmp .
# Install it using 'installpkg'.
