[gentoo-dev] ebuild dependencies

[gentoo-dev] ebuild dependencies

[Zach Forrest]

After looking through some ebuild files, I have noticed that some of the 
depends entries have a question mark after them. I'm not exatly sure 
what this means, but it seems like an optional dependency, maybe for a 
use flag?

Example:
decss? ( media-libs/libdvdcss )

If someone wouldn't mind giving me a quick how-to, I would really 
appreciate it.

Thanks.

Zach

If decss is set as USE flag, enforce the media-libs/libdvdcss dependancy

it means if you have decss in your USE flags, media-libs/libdvdcss will
be a dependancy, else not ....

I guess you could do something like this:

grep -q "\<gnome\>" /var/db/pkg/dev-python/pygtk-2.0.0*/USE

and issue a warning/error to the user explaining the situation if gnome 
support was not enabled for pygtk?
