I tried to explain this before. See |
| 24 |
<http://article.gmane.org/gmane.linux.gentoo.devel/52316/match=use+options>. |
| 25 |

Having an ordinary use flag for each library may work well enough when there |
| 27 |
are less than three libraries that provide a certain functionality, although |
| 28 |
with 2 old-style use flags you already have one bogus fourth option. Default |
| 29 |
should not be an option of its own; one of the three options should be the |
| 30 |
default. |

I'm not trying to hijack this thread. I'm just injecting one message pointing |
| 36 |
this out as something I think could benefit from my proposal. |
| 37 |
|
| 38 |
A few real examples may go a long way to explaining something. |
