The first section of this package processes a large subset of the -mdoc macro
functions into HTML. All of the commonly used requests are implemented.

The second section implements -man (-man.old) macros. These are trivial
compared to -mdoc.

NOTES:
	The initial purpose of these macros is to support distrib/notes.
	It's very close, but not quite ready to do all of the man pages.

	See src/distrib/notes/Makefile.inc for important groff command
	examples. For HTML generation it is important to turn off overstrike
	modes with -P-b -P-u -P-o.


TODO:
	There are a few internal macros and other symbols that don't contain
	an embedded `-'.

	Need a tbl(1) command that generates html tables from tbl(1)
	input. (Partially written.) For now, we just switch into <pre>
	mode on .TS or .PS. Tbl input is very uncommon these days, anyway.
	(-mdoc has the .Bl -column list, which eliminates most requirements
	for tbl)

	We should probably end all the html pages with an upward
	pointing "contents" link, except right now there is nothing
	to point to.

	We need "intro" or "contents" pages for each man/man? (man/html?)
	section.

	WARNING! If you add a callable macro (or define an old one that
	was missing) it MUST have a doc2html@@ alias. (Scan for @@ to see.)
