Many programs that include an interpreter can accept a script either
as a file or as a string passed through the command line, with or
without a special command-line option.  One example is Awk, another is
Python.

In any case, the process-send-string method sounds like the best
alternative to me, so I hope someone will explain how to do it
correctly (does mutool have some forum where you could ask
questions?).  If that is unworkable for some reason, I guess
generating a temporary file with the script is the next thing I would
try.

Thanks.
