+freenx (Free implementation of the NX Server)
+
+Freenx is an application/thin-client server based on nx technology.
+NoMachine nx is the next-generation X compression and roundtrip suppression 
+scheme. It can operate remote X11 sessions over 56k modem dialup links or 
+anything better.  This package contains a free (GPL) implementation of the 
+nxserver component.
+
+Because a nx user with some default settings is needed for the server to 
+build, a script, preinstall.sh, is provided to be executed (sh preinstall.sh) 
+before running the slackbuild: it's pretty straightforward in his functions, 
+have a look at it.  Also, after installation, you will need to run (as root)
+"nxsetup --install" to complete the setup process.
+
+This requires nx.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.  Line
+# up the first '|' above the ':' following the base package name, and the '|'
+# on the right side marks the last column you can put a character in.  You must
+# make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':'.
