the M4 macro compiler came fairly late in Sendmail's evolution. in the
OLD days, editing the sendmail.cf file directly was all you had. you
just about needed a PhD in that stuff to do anything beyond the simplest
tweaks, although with the O'Reilly Sendmail book ("bat book"), you could
get away with assembling bits and pieces of other peoples hacks for most
any sane configuration.
