# Usage: makemake {<program name> {<F90 compiler or fc or f77 or cc or c>}}
#
# Generate a Makefile from the sources in the current directory.  The source
# files may be in either C, FORTRAN 77, Fortran 90 or some combination of
# these languages.  If the F90 compiler specified is cray or parasoft, then
# the Makefile generated will conform to the conventions of these compilers.
# To run makemake, it will be necessary to modify the first line of this script
# to point to the actual location of Perl on your system.
