1 | # Having a separate GNUmakefile lets me `include' the dynamically |
| 2 | # generated rules created via Makefile.maint as well as Makefile.maint itself. | |
| 3 | # This makefile is used only if you run GNU Make. | |
| 4 | # It is necessary if you want to build targets usually of interest | |
| 5 | # only to the maintainer. | |
