Yeah, me too. Who wants to rewrite the code for the relativistically invariant two-particle collisions used to do simulations of pair productions, and for which the physics constraints are applied following the collision to test theories. Oh yeah: at the same time you should convert the code for the reduction of the soloution of 12 Feynman-Dyson diagrams to a set of constraint matrices used by the first code you convereted. Good luck writing code to solve Clifford algebras in C; the original FORTRAN code was written from the output of a Reduce calculation. This type of code desn't tend to exist in C or C++ ...at least until after f2c has been run on it. 8-). Even then it ends up being largely unreadable. 8-(.
