All in the readme in the dir,
If you want to broadcast to listeners, you'll need:
* 90Mhz or faster server, running one of Windows 95, 98, NT, 2000, ME,
Mac OS X, Sparc Solaris 2.7+, FreeBSD 4.x+, or Linux with a libc6 kernel.
* 14kB of memory for every listener you want to broadcast to (i.e. 1,000
listeners means you need 14 Megabytes of RAM), plus whatever your
operating system needs for overhead, plus 1.5MB for the server's
base requirements. Don't set the listener count higher than you need,
it just screws things up.
