PLP -- the Portable Line Printer spooler system

PLP is a portable, reliable implementation of the BSD Line Printer Spooler (LPD) system. Some new features that improve on the features of most BSD LPD implementations:

The code has been extensively ported, and uses GNU autoconf to determine its portability options.

It's in constant use on SunOS 4.1.x and Solaris 2.x, so it will definitely work there. It's also been checked for memory leaks and so on using Purify.
