***********************************************************************
$0: jack-audio-connection-kit not found.

If you want $PRGNAM to be able to make sound, you must install
jack-audio-connection-kit before running this script.

If you want to build a dedicated server, you don't have to install
jack-audio-connection-kit. Instead, export SERVERONLY=yes in the
environment. See SERVER.txt for details.
