NEVER, EVER, INSTALL THIS ON A REAL SCO SYSTEM! IT WILL BREAK IT!

This is a simple minded stand in for /shlib/libnsl_s found on SCO/SVR3
systems. This library is responsible for providing the user level
API for the XTI/TLI networking. The stand in provides sufficient
functionality to handle UDP (e.g. DNS look ups) and outgoing TCP
connections. Incoming TCP _may_ work but this hasn't been tested
at all. Many things that should strictly fail will quietly recover
using this library and the iBCS module. Where errors occur you
may not get the correct repsonse (for instance you get "No such
device or address" instead of "Connection refused") however this
is not a problem where connections succeed. Once the connection
is established there is little that could go wrong.

A "make install" will install protlib_s as /shlib/libnsl_s.emu and,
if a /shlib/libnsl_s doesn't already exist, will create a symlink
pointing at /shlib/libnsl_s.emu. At the same time libnsl_s.debug
will be copied to /shlib/libnsl_s.debug. This version of the library
will write a line to stderr for every library function called. If you
have problems you can use this to get an idea of what needs to be
implemented to get any further.

This library needs to be built using SYSV tools on a SYSV system. Sorry.
