Hello Olivier,

I've removed this option and added CiceroExecutable and
CiceroExecutableLog. I've installed Cicero with French
mbrola and it seems to work very well. I've tested it with
spd-say and speechd-el.

Another problem which I encountered were crashes of the output
nodule caused by uncaught SIGPIPE signal (for example if Cicero can't
open sound device), so I've added code so that now both threads
ignore SIGPIPE. I've seen all IO return values are carefully checked,
so this should not be a problem.

We will be shortly doing a release of Speech Dispatcher (most likely
after the weekend). Could you please download the latest CVS and check
if I didn't introduce any bug?

Thanks,
Hynek Hanke
