# Slackware SlackBuild script 
# ===========================
# By:        Eric Hameleers <alien@slackware.com>
# For:       vnc
# URL:       http://www.realvnc.com/
# Needs:     Fairly recent version of X
# Changelog:
# 4.0-1:     16/oct/2004 by Eric Hameleers
# 4_1_1-1:   30/apr/2005 by Eric Hameleers
#            * Unfortunately, there's no updated documentation tarball yet.
# 4_1_1-2:   02/aug/2005 by Eric Hameleers
#            * Forgot to add the vnc extension for X to the package.
# 4_1_1-3:   12/aug/2005 by Eric Hameleers
#            * Somehow the permissions of the package were messed up, so that
#              after installation,. / was group-writable and Sendmail
#              refused to run. Fixed this in _vnc.tar.gz.
# 4.1.2-1:   21/nov/2006 by Eric Hameleers
#            * The 4.1.2 is a security fix.
# 4.1.2-2:   08/jan/2007 by Eric Hameleers
#            * Fixed group-writable directories in the package (sendmail would
#              stop working after install of the vnc package).
#
# -----------------------------------------------------------------------------
# 
# Issue 'sh SlackBuild --cleanup' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'.
