I found this TUHS thread from 2019:
https://tuhs.org/mailman3/hyperkitty/list/tuhs@tuhs.org/thread/GPFOZNHNX2JO…
in which Andy Hall's 1972 memo on M6 is referenced:

For a few years now I've used it to generate two man pages from a single

The Wikipedia article on macroprocessors says that M6 was written in
the 1960s by McIlroy, Morris, and Hall, based on GPM and Trac, written
in Fortran and ported to v2 Unix.
M4 was written in the 1970s by Kernighan and Ritchie in C and is still
around, notably as impenetrable magic in GNU autoconfig and sendmail
config files. It looks a lot like GPM.
The only thing I stubbed my toe on is m4's appropriation of common
English words for its command language. A prefix sigil before such
words would have been a better choice. But I got around that, too.

In 1997, when CSS was just beginning, long before
https://en.wikipedia.org/wiki/M4_%28computer_language%29 was started in
2004, and subsequently illustrated m4 macros for creating HTML, I
started using m4 macros extensively to define Web pages in such a matter
that they could mimic appearance of other pages, and taught others at
our startup to use those macros, so that our customers could use our
software while retaining appearance consistent with the rest of their
pages. Another way to think of the macros is that they comprise a static
content management system – the content is stored in m4 files, which are
transformed into HTML in advance, vs. more dynamic page generation in a
typical content management system.

show remnants of customer pages created with those m4 macros.
