couple of macros from -mS (.Li/Le for lists which were similar to MM's)
for big documents, and the UCB -man for really simple things. It
becomes a 'less is more' sort of thing - -mm and too complicated and I
was not writing BTL tech memos, and after I did not my thesis, I did not
need Eric's work (which was perfect for a UCB thesis).
For me it was ROFF (V5), -man (V6), -ms (V6). These days I don't need
markup any more; the most complicated things I write are letters using
TextEdit on the Mac, and C/Perl/etc with VI :-)
Actually on the odd occasion I need markup it's "groff -ms -Tps" on
the FreeBSD box.
