The result is the same. I prefer to use files, because they yield better |
| 25 |
cvs diff results. Seeing someone change the REQUIRED_USE line involves |
| 26 |
looking over the complete line to find the changes. We could split the |
| 27 |
line over multiple lines to make it easier, but then we could just use a |
| 28 |
flat file. Well we're talking about a couple of flags here, but we don't |
| 29 |
know what we'll use these REQUIRE_USE for in the future |
