Authors of txt2pdbdoc (formerly unixdoc)

Paul J. Lucas.  Performed major clean-up of the text-to-Doc code.
Converted it from C++ to C since C++ isn't really needed for this code and
having it in C increases portability.  Wrote documentation.

Christopher Heschong.  Original author for HTML-to-text conversion.

Harold Bamford.  Fixed portability problem with sizeof struct's.

Rick Bram & Florent Pillet.  Original authors.
