Useage: festival_server [-p PORT] [-l LOGDIR] [-show] [FESTIVAL]
Run festival as a server
-p PORT Port to listen on, defaults to 1314
-l LOGDIR Record what is happening in the given directory
-c CONFIG File of Scheme code to be loaded by festival
to set access control and preload voices.
-show Print the configuration file which would have
been used then exit.
FESTIVAL Festival itself if it isn't on the PATH.
If no CONFIG is given a default will be created. This is very minimal and
you should certainly create one which better reflects your needs.
Use the -show argument to get the default CONFIG file as something to work
from.
