/*
 * FILENAME		:	Main.c
 * DESCRIPTION	:	The purpose of clibstuf is to make sure that Perl, cgi2perl and
 *                  all the perl extension nlm's (*.NLP) use the Novell Netware CLIB versions
 *                  of standard functions. This code loads up a whole bunch of function pointers
 *                  to point at the standard CLIB functions.
