Current libunique users

Summary

Unique is a library for writing single instance application. If you launch a single instance application twice, the second instance will either just quit or will send a message to the running instance.

Note: From http://mail.gnome.org/archives/desktop-devel-list/2007-July/msg00048.html:
"the functionality (of LibUnique) is targeted for inclusion in GTK+ - but only when GTK+ gets an "application" class (bug 127958) from which a single instance application class should inherit".
