I would like to build sane-backend only for one specific scanner. However, there are a huge lot of different USE flags for other scanners that are already switched on by default.
Is there any easy way to switch them off? Something like: media-gfx/sane-backends -sane_backends* sane_backends_hp Exactly that way does not work, but may be something like that... ...instead of directly switching off every one of them.
