Indeed, there has been the thread
     "Incorporating TeX into Custom-made Programs"
which I recommend very much to read.
Especially Karl's answer as of Feb 27 has some similarities
with my previous posting, but also interesting differences.
E.g., Karl and I referred to appendix G of the TeXbook.
Karl recommended to re-implement the algorithm,
while I rather didn't :-)
(And I thought that appendix G is almost impossible to
understand without reading certain parts of chapters 17f.
-- not the "how to" parts, rather those dealing with spacing
[including "atoms"] and choosing sizes in a general way
["styles"].)
The other postings of "Incorporating ..." date from Feb 16.
(I found this in tidying up my texhax mailbox.)

I have realized that alignment can be very important
in math parts -- "equation arrays", "commutative diagrams",
"cases" ... To avoid macro packages here, you would have
to read TeXbook pp. 235 on \halign.

All the best,
   Uwe.
