# Slackware SlackBuild script 
# ===========================
# By:        Eric Hameleers <alien@sox.homeip.net>
# For:       libvncserver
# URL:       http://libvncserver.sourceforge.net/
# Needs:     
# Changelog:
# 0.8pre-1:  24/feb/2005 by Eric Hameleers <alien@sox.homeip.net>
#            * Initial build.
# 0.8pre-2:  03/jan/2006 by Eric Hameleers <alien@sox.homeip.net>
#            * Added SDLvncviewer binary.
# 20060425-1:25/apr/2006 by Eric Hameleers <alien@slackware.com>
#            * Updated the CVS snapshot. Since Johannes calls every snapshot
#              "0.8pre" I decided to use a "yyyymmdd" scheme for my package.
# 
# Run 'sh SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'.
