+  MFEM is a free, lightweight, scalable C++ library for finite element
+methods.
+
+
+  Building options that can be set using the environment variable:
+  - OMP=yes, use OpenMP.
+  - MPI=yes, use MPI (requires a MPI implementation either mpich or
+  openmpi and the hypre and metis package.
+  - CUDA=yes, requires the CUDA toolkit.
+  - TESTS=yes, to run the tests.
+
+  Compiling the examples:
+  # mkdir mfem-examples; cd mfem-examples
+  # cp -av /usr/share/mfem-4.5/{data,examples} .
+  # make -C examples
+  # make

+# 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.
