This output is exactly what my patch gives, but it currently works by |
| 17 |
inspecting IUSE. However, it should be possible to indirectly pull the |
| 18 |
information from the above flags instead. Adding support for a |
| 19 |
USE_EXPAND_HIDDEN var should cover USERLAND and friends as well (although |
| 20 |
those would still need to be defined in IUSE_USERLAND="...") |

This still doesn't cover the discrepencies in behaviour between different |
| 28 |
packages though. How to handle that in the short term? einfo and/or ewarn? |
