This directory contains some mu-law encoded SunOS 4.1 sound files. If you're running XEmacs on the console of a SparcStation or SGI machine, you can use these sounds to replace the default beep. See the documentation of the `sound-alist' variable, and the functions `load-default-sounds' and `load-sound-file' from lisp/prim/sound.el.
