No worries, I know how that goes!

Sounds good.  Please let me know of any changes that might need to be
made in the architecture.

You're welcome!  Getting this working was a bit of a nightmare,so the
appreciation is appreciated.

Note:  I've just checked in a couple more changes so that it runs on
parallel.  Currently the energies are summed incorrectly with MPI for
velocity verlet (I'm getting kinetic energies correct, but
temperatures are scaled by 1/np and potential energies are scaled by
np), but they are correct for leapfrog.  I'll try to drill down to get
it correct when I have the opportunity.

Also, if anyone else wants to try it, the -correct- repository
location is actually:

git://git.gromacs.org/~mrshirts/gromacs_mrs.git

(I'm still getting a hang of git . . .)
