qt3 and qt4 is being used there already and it is obvious |

qt3 - enable optional qt3 support |
| 21 |
qt4 - enable optional qt4 support |
| 22 |
|
| 23 |
when both are possible its the maintainers decision, would look something |
| 24 |
like this: |
| 25 |
|
| 26 |
qt4? ( =x11-libs/qt-4* ) |
| 27 |
!qt4? ( qt3? ( =x11-libs/qt-3* ) |
| 28 |
|

Why you ask? Because a user does not care if packageX uses qt3 or qt4, he |
| 31 |
just wants to use it. |
| 32 |
|
| 33 |
But why do we have two useflags then? |
| 34 |
Because the user should be able to disable optional support for either qt3 |
| 35 |
or qt4 or both for every package. |
| 36 |
|
| 37 |
Disabling all optional qt4 support is only conveniently possible with a qt4 |
| 38 |
flag. Same for qt3. |
| 39 |
We need separate flags here, otherwise you can just use one flag for |
| 40 |
everything, it does not make sense to have two flags when one cannot be |
| 41 |
used because the other is ambiguous. |

This "add a new package to portage" is not really the gentoo spirit of |
| 47 |
following upstream tarballing, in my opinion. |

We have 36 qt-use-packages, so we could have 36 different flags in the |
| 54 |
end ;) |
| 55 |
Trying to reach a consensus on the mailing list is a better idea imo. |

| 60 |
right you are. And since we already have a qt3 and a qt4 useflag in the tree |
| 61 |
it is a good move to do this right. |
