I think it should be supplemented with a tool that would scan the entire |
| 28 |
database of packages, not just the ones installed. Whenever I'm considering |
| 29 |
a change, of whatever sort, I want to know the consequences. |

Unless I'm mistaken, there's no way to find out what USE flags a package |
| 32 |
uses without installing it first. I recently discovered gentoo-portage.com, |
| 33 |
which is useful but it's organised the other way around, naturally enough, |
| 34 |
so it still involves much scanning. |
