| # Recursive make is considered harmful: |

| # |
| # For now this Makefile uses explicit dependencies. The project |
| # hasn't grown big enough to need something complicated, and the |
| # dependency tracking files are an ugly annoyance. |
| # |
| # This file includes */module.mk files which add on to variables: |
| # FOO += bar/baz |
| # |
| # |
| # Set (or uncomment) SKIP if you wish to avoid something. |
| # For example, you may prefer the /bin/kill from util-linux or bsdutils. |
