mmmm
(pronounced with rising inflection, as if pausing before critisism)
is a typesetting and layout methodology using POSIX tooling.
my working copy would take a few more rounds of implementation to be worth presenting complete:
here I'll lay out the basic techniques that you might use as a base for
a system fit for similar purposes.
if you have a terminal available you may be surprised to see it already installed:
$ which m4
this will include downsides of m4 features
and recourse possible by composition of other POSIX tools.
in fact, no implementation is provided:
only an outline.
