+barrier: barrier (Synergy Fork)
+barrier:
+barrier: Eliminate the barrier between your machines.
+barrier: Barrier is KVM software forked from Symless's synergy 1.9 codebase.
+barrier: Synergy was a commercialized reimplementation of the original
+barrier: CosmoSynergy written by Chris Schoeneman.
+barrier: Whereas synergy has moved beyond its goals from the 1.x era, Barrier
+barrier: aims to maintain that simplicity. Barrier will let you use your
+barrier: keyboard and mouse from machine A to control machine B (or more).
+barrier: It's that simple.
