-      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: https://www.gromacs.org/about.html for details.
