| 8 | # that are generated (by invoking ocamllex |
| 9 | # or menhir) |
| 10 | # |
| 11 | # MODULES : a list of the modules (without extension) |
| 12 | # that should be linked into the executable |
| 13 | # program. Order is significant. |
| 14 | # |
| 15 | # EXECUTABLE : the base name of the executables that should |
| 16 | # be produced. Suffixes $(BSUFFIX) and $(OSUFFIX) |
| 17 | # will be added to distinguish the bytecode and |
