Logitech Harmony remote control software
http://www.sourceforge.net/projects/concordance/

This software supports programming Logitech Harmony remote controls.
While currently in beta, this software already provides most of the
functionality of the Windows software provided by Logitech, but is much
smaller and cross-platform. This packages requires libraries from the
companion libconcord packages and is also supplemented by the consnoop
package.
