Yes, that is my intention - the gromacs package is always the latest
(stable) release available. The question was whether to package also an
older release version.

The packages contain everything in both single and double precision
(e.g. mdrun & mdrun_d), and also mdrun in MPI-versions (mdrun_mpi and
mdrun_mpid). When the gromacs makefile is modified to have a make
parallel option to obtain also the couple of mpi-enabled analysis tools
I will add them to the package.

No hurry - I'm using rc3 for now. Once the final comes out it won't be a
big thing to release new packages.

The main question for now has been where to put the binaries, since
there are so many of them and some of them have very general names that
might clash with other packages. The solution is very likely environment
modules.

I'll send more info about the package when it's accepted. It will be
available at least for RHEL 4, 5 and Fedora 9 and 10.
