I could do as much as I wanted with EPS using Text_IO, except that I needed
to seek back to the start of the output file to insert a couple of values
that only became known at the end of the plot.  I already had a simple POSIX
subset package, so that was trivial to do as well.

Have a look in http://www.findlayw.plus.com/EPS/

That code is not self-sufficient, as the packages are part of a larger
program, but it should be clear enough how to extract the
context-independent stuff.
