XmdS – eXtensible multi-dimensional Simulator

XmdS ^[1] looks like an interesting package:

XMDS is a code generator that integrates equations. You write them down in human readable form in an XML file, and it goes away and writes and compiles a C++ program that integrates those equations as fast as it can possibly be done in your architecture.

Personally I thought it might be drawing a long bow to call XML “human readable”, but some of the examples ^[2] aren’t too bad at all.
