[gentoo-dev] ebuild USE priority

[Erik Grinaker]

Hi all

I'm making an ebuild here, and have run into a small "problem".

The ebuild is for the Unix Amiga Emulator, or uae for short. uae allows
you to select which backend to compile against during ./configure, and
you can choose *either* x, svgalib, ncurses or sdl.

If a user has, say, both X and svga in his USE variable, how do I
determine whether to use X or svgalib for backend?

According to what I believe is common sense I would prioritize them as
X, sdl, svga, ncurses - but is there a better way to do this, or do I
just go by feeling?
