Unfortunately Cyrano JA is Windows only. I tested the Linux compiles from Cyrano's author and it kept crashing or losing on time, or disconnecting or whatever. I'll test it when it becomes stable enough.

[Günther Höhne]

ok, I saw on the website from Harald Johnson, a linux compile from Cyrano, too bad it does not work well.

i'll have a closer, and see if i can compile it myself and fix the problem.
