This package implements a library of functions that was intendend to help creating client-server packages using TCP/IP or other file descriptor based links. Use of this package for development of new software is not currently recommended. Much of the documentation is probably outdated. Be sure to read the file NEWS, and trust it more than the man pages. Trust doc/MANUAL.sv even less than the man pages. Better still: use the source code instead of the documentation.
