2.97 frystyk 17: This file makes up for the differencies in the systems and platforms supported
18: by libwww. On Unix, it is a question of <A HREF="../../INSTALL.html">using
19: autoconf</A> to figure out what environment we are in. This is done by running
2.113 frystyk 20: the configure script which creates a <CODE>wwwconf.h</CODE> file. This
2.97 frystyk 21: configuration include file contains a large set of macro definitions telling
22: what features we have and don't have. On platforms not supported by autoconf
23: (Windows, Mac, VMS etc.) you will find the information normally contained
2.113 frystyk 24: in the <CODE>wwwconf.h</CODE> file directly included below. The
2.97 frystyk 25: <A HREF="#Platform">second part of this file </A>uses all the information
2.113 frystyk 26: that we either have from the wwwconf.h file or directly coded and actually
2.97 frystyk 27: does the includes etc.

429: number is a VMS channel number, so we make the @@@ HORRIBLE @@@ assumption
