All documentation with extension '.doc' or '.desc' are sgml documents
according to the document tyep definition in 'doc.dtd'.
To print it:

	1. Create the document parser for doc.dtd with

		sgml doc.dtd
	
	2. Parse the document ???.doc with the file
	   'lib/sgml/replace/doc-ms' as replacement file

		doc.asp -r lib/sgml/replace/doc-ms ???.doc > ???.tr
	
	3. Put the resulting file through troff with the macros
	   in  'lib/sgml/tmac/mac/documentation'

		troff -ms lib/sgml/tmac/mac.documentation ???.tr
	
	4. Print the troff output following local conventions.
