# Usage: makemake {<program name> {<F90 compiler or fc or f77 or cc or c>}} |
| 4 |
# |
| 5 |
# Generate a Makefile from the sources in the current directory. The source |
| 6 |
# files may be in either C, FORTRAN 77, Fortran 90 or some combination of |
| 7 |
# these languages. If the F90 compiler specified is cray or parasoft, then |
| 8 |
# the Makefile generated will conform to the conventions of these compilers. |
| 9 |
# To run makemake, it will be necessary to modify the first line of this script |
| 10 |
# to point to the actual location of Perl on your system. |
