def say(message):
''' Speak a message.
Runs a "say" program, passing the message on the command line.
Because most systems are not set up for speech, it is not an
error if the "say" program is missing or fails.
It is often easy to add a "say" program to a system. For example,
a linux system using festival for speech can use a one line script:
festival --batch "(SayText \"$*\")"
Depending on the underlying 'say' command's implementation, say()
probably does not work unless user is in the 'audio' group.
