# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        tigervnc
# Descr:      VNC server and client
# URL:        http://tigervnc.org/
# Needs:      
# BuildNeeds: jdk (only when building the java applet)
# Changelog:  
# r4126-1:    31/Aug/2010 by Eric Hameleers <alien@slackware.com>
#             * Initial build.
# r4126-2:    02/sep/2010 by Eric Hameleers <alien@slackware.com>
#             * Fix a syntax error in thye doinst.sh script
# 1.0.90-1:   14/may/2011 by Eric Hameleers <alien@slackware.com>
#             * Update to 1.1.beta1
# 1.1.0-1:    14/nov/2011 by Eric Hameleers <alien@slackware.com>
#             * Update to 1.1.0
# 1.2.0-1:    23/jun/2012 by Eric Hameleers <alien@slackware.com>
#             * Update.
# 1.1.0-2:    28/jul/2012 by Eric Hameleers <alien@slackware.com>
#             * Build 1.1.0 again, using a revised script which can be used
#               on Slackware 14 as well.  Also, enable compositing in the
#               server.  Abandon the tigervnc-1.2 branch for now, because
#               the fltk based viewer rewrite is not yet fully functional.
# 1.1.0-3:    22/may/2013 by Eric Hameleers <alien@slackware.com>
#             * Build 1.1.0 again, on slackware-current (nee 14.1) with new
#               X.Org 1.13 patches.
# 1.1.0-4:    11/oct/2013 by Eric Hameleers <alien@slackware.com>
#             * Build 1.1.0 again, on slackware-current (nee 14.1) with new
#               X.Org 1.14 patches.
# 1.3.0-1:    12/dec/2013 by Eric Hameleers <alien@slackware.com>
#             * Update.  All my issues except copy/paste from local to remote
#               seem to have been addressed in 1.3.0.
#               Build against private versions of libjpeg-turbo and fltk,
#               in order to eliminate external dependencies.
# 1.4.3-1:    11/apr/2015 by Eric Hameleers <alien@slackware.com>
#             * Update.
# 1.4.3-2:    03/may/2015 by Eric Hameleers <alien@slackware.com>
#             * Rebuild for slackware-current (fix libgcrypt.so library error)
# 1.5.0-1:    14/jul/2015 by Eric Hameleers <alien@slackware.com>
#             * Update.
# 1.5.0-2:    24/aug/2015 by Eric Hameleers <alien@slackware.com>
#             * Rebuild was needed on slackware-current.
# 1.5.0-3:    26/aug/2015 by Eric Hameleers <alien@slackware.com>
#             * I uploaded the wrong package so I needed to update the BUILD.
# 1.5.0-1:    07/nov/2015 by Patrick Volkerding <volkerdi@slackware.com>
#             * Removed bundled FLTK and libjpeg-turbo builds.
#             * Reset build to -1 for inclusion in Slackware's /extra.
# 1.6.0-1:    22/feb/2016 by Patrick Volkerding <volkerdi@slackware.com>
