+  longDescription = ''
+    GROMACS is a versatile package to perform molecular dynamics,
+    i.e. simulate the Newtonian equations of motion for systems
+    with hundreds to millions of particles.
+
+	It is primarily designed for biochemical molecules like
+	proteins, lipids and nucleic acids that have a lot of
+	complicated bonded interactions, but since GROMACS is
+	extremely fast at calculating the nonbonded interactions (that
+	usually dominate simulations) many groups are also using it
+	for research on non-biological systems, e.g. polymers.
+
+	GROMACS supports all the usual algorithms you expect from a
+	modern molecular dynamics implementation, (check the online
+	reference or manual for details), but there are also quite a
+	few features that make it stand out from the competition.
+
+	See: www.gromacs.org/About_Gromacs
