synergy for Debian
------------------

Synergy works with non-Debian machines; for more information, see the
project website.  At the time of writing packages/installers for
synergy were available for:

  * Windows
  * MacOS X
  * RPM- and deb-based Linux
  * Android
  * iOS

Synergy should work on all systems that use the X Window System, but
you may have to compile it yourself. The source code is also available
at the above address.

synergy-plus
------------

There was a relatively short-lived fork of synergy called
"synergy-plus" that formed when upstream development slowed.  As of
this moment, the two projects have re-merged; essentially, the
synergy-plus team has taken over development.  This package contains
synergy as distributed by the merged project.

Crypto
------

As of version 1.4.12, synergy has included an option for encrypting
the data sent between hosts.  This support features a home-grown
crypto protocol implemented on top of the Crypto++ library, and has
already been cracked once.  See:
