I searched around but didn't see anything already in the code. I picked up
a program by Steven Pemberton called enquire several years ago. You can get
the latest version here:
It's kind of cool because it's both a C program and a shell script. You
execute it with sh to compile it and run some tests.
(I wonder if using it to generate values for use in Python - perhaps an
adjunct to mathmodule.c for the floating point stuff - would be worthwhile?)
