# Slackware SlackBuild script 
# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        nx
# Descr:      a proxy system for X Window
# URL:        http://www.nomachine.com/
# Needs:      
# Changelog:  
# 1.5.0-1:   14/Aug/2005 by Eric Hameleers <alien@sox.homeip.net>
#            * Initial build.
# 1.5.0-2:   18/Aug/2005 by Eric Hameleers <alien@sox.homeip.net>
#            * Updated to first maintenance release; added patched version of
#              esd to get sound in the Windows/Mac client
#              (the default esd is broken).
#              If you want sound in KDE, use "UNIX/Custom" in nxclient and the
#              command line is "nxesddsp startkde". Then, configure KDE to use
#              the ESD and enable networked sound.
# 1.5.0-3:   01/Sep/2005 by Eric Hameleers <alien@slackware.com>
#            * Updated nxdesktop. Also, freenx is patched so that it runs
#              "nxesddsp" automatically for KDE sessions, so sound should work
#              with the default client configuration for KDE.
# 1.5.0-4:   03/Sep/2005 by Eric Hameleers <alien@slackware.com>
#              This time, nxesddsp should really work :-/ Forgot to use the
#              patches, *and* forgot to copy the patched libs.
# 3.2.0-1:    16/Nov/2008 by Eric Hameleers <alien@slackware.com>
#             * Update to 3.2.0.
# 3.3.0-1:    30/dec/2008 by Eric Hameleers <alien@slackware.com>
#             * Update to 3.3.0.
# 3.3.0-2:    27/jan/2009 by Eric Hameleers <alien@slackware.com>
#             * 3.3.0 service release by NoMachine updates several components
#               (nxcompext, nx-X11, nxagent, nxcompshad).
# 3.4.0-1:    18/dec/2009 by Eric Hameleers <alien@slackware.com>
#             * 3.4.0 service release by NoMachine updates several components
# 3.4.0-2:    04/jun/2010 by Eric Hameleers <alien@slackware.com>
#             * 3.4.0 service release by NoMachine updates several components
# 
# Run 'sh nx.SlackBuild' to build a Slackware package.
# The package (.tgz) plus descriptive .txt file are created in /tmp .
# Install using 'installpkg'.
