If you (or anyone else) are serious about modifying mm (or any other troff
macro package) I would recommend that you purchase our ruggedized version of
troff. The following features alone will probably make it worth your while:
- we have added syntax checking to troff (optional, of
course) and have fixed numerous SYNTAX ERRORS in
the original -mm; you get our fixed version;
- we have macro call tracing, so you can see what nested
macros each macro really calls;
- we have added long name facilities for registers, macros
and other named objects, so that you can use meaningful
names in any macros that you write or modify, instead of
the original two-character names like "}I" or "]Z".
- Substantial documentation, much of it written from the
ground up rather than just reprinting the original AT&T
documents.
Lots of other features, too. It runs on UNIX (Suns, Amdahls, and most other
modern UNIX boxes) and on MS-DOS. Please contact us for marketing
information, at "mail@sq.com" or {utai|utzoo}!sq!mail. Or call 416-963-8337.
U.S.A. customers can call us on our AT&T Co-Marketing number, 800-387-2777.
Hope this information is helpful.
