Is it really true, that mh-format does not have a multiply function?
Huh ... it does not! I guess one of those old geezers did not think it
was necessary. Maybe it would be worth it to implement that at some point.
Rather than multiply, may I susggest another funncton, which would give
mutliply and much more.
%(exec procedure_name)
It would exec procedure_name and return its stdout. It would not redirect
stderr. For each component, comp, of the messages, it would define an
environment variable, NMH_FORMAT_comp, whose value was the content of that
component.
A non-zero exit status would be an error.
Such a function would let the ordinary bloke define her own format without
having to learn the intricacies of mh-format. She could use her favorite
scripting language, be it python, bash, csh, perl, Java, or even C or C++.
And it would let the non-orginary bloke do things that mh-format
can't do.
