# ===========================
# By:         Eric Hameleers <alien@slackware.com>
# For:        freenx-client
# Descr:      client for the FreeNX server
# URL:        http://freenx.berlios.de/
# Needs:      NX libraries from NoMachine (nxssh and nxproxy to be exact).
# Changelog:  
# 0.9-1:      31/Dec/2008 by Eric Hameleers <alien@slackware.com>
#             * Initial build.
# 
# Run 'sh freenx-client.SlackBuild' to build a Slackware package.
# The package (.tgz) and .txt file as well as build logs are created in /tmp .
# Install it using 'installpkg'. 
#
