Optional dependencies...

I'm wondering if there is a way to require one of two optional dependencies in a PKGBUILD.  For example, mftrace requires that you install either autotrace or potrace.

If this isn't implemented, I think it would be a good idea.  Like dep=('autotrace/potrace')

Also, it would be cool to be able to have recommended but optional packages, and ask the user if he wants to install recommended packages as well.

What do you guys think?

Re: Optional dependencies...

Well, right now you can use "provides" to have a sort of optional depends.

For example, the potrace and autotrace packages could both be built to provide "raytracer". Then the mftrace package would simply depend on a "raytracer".

Not quite the same, but it fills in some of the need.

Re: Optional dependencies...

if they do not provide the same thing (e.g. x-server), but the pkg you want a dependency for needs to link to them, then the best way to go is to build it against both and make both a dependeny of it
