+%description
+GROMACS is a versatile and extremely well optimized package to perform
+molecular dynamics computer simulations and subsequent trajectory analysis.
+It is developed for bio-molecules like proteins, but the extremely high
+performance means it is used also in several other field like polymer chemistry
+and solid state physics.
+This package provides single and double precision binaries.
+The documentation is in the package gromacs-common.
+mdrun has been compiled with thread parallellization, so it runs in parallel
+on shared memory systems. If you want to run on a cluster, you probably want
+to install one of the MPI parallellized packages.
+N.B. All binaries have names starting with g_, for example mdrun has been
+renamed to g_mdrun.
