GROMACS shared data and documentation

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 includes architecture independent data and HTML documentation.
