-ms or -mm macro package ?

I don't think the -mm macros work with 4.1BSD nroff but someone
else probably has a better answer to this question.

If you're converting to 4.2BSD then you could just install the BRL
UNIX System V user environment on top of your O.S. and use that.

Otherwise, with a moderate amount of work you could adapt the USG
nroff (and other text-processing tools) to work on 4.1BSD and replace
those shipped with the system.

I think this is all worth doing.  The -mm macros are much better than
the -ms ones, in my opinion.  You should also realize that the -ms
macros do not come with UNIXes supplied by Western Electric starting
with UNIX System III (actually System III had a nice version hidden in
/usr/doc somewhere, but it was unsupported).
