define REMHOS_HELP_MSG

Remhos makefile targets:

   make
   make status/info
   make install
   make clean
   make distclean
   make style

Examples:

make -j 4
   Build Remhos using the current configuration options from MFEM.
   (Remhos requires the MFEM finite element library, and uses its compiler and
    linker options in its build process.)
make status
   Display information about the current configuration.
make install PREFIX=<dir>
   Install the Remhos executable in <dir>.
make clean
   Clean the Remhos executable, library and object files.
make distclean
   In addition to "make clean", remove the local installation directory and some
   run-time generated files.
make style
   Format the Remhos C++ source files using the Artistic Style (astyle) settings
   from MFEM.
