+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 and is a community-driven project.
+
+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 and fluid dynamics.
+
+
+Optional dependences:
+For run-time detection of hardware capabilities set HWLOC=yes. This 
+requires hwloc.
+To enable MPI set PARALLEL=yes. This requires a MPI implementation 
+either openmpi or mpich.
+For enabling CUDA set CUDA=yes. This requires the CUDA SDK.
+To enable OpenCL set OPENCL=yes. This requires a OpenCL 
+implementation.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
