For metalinks and such, yeah. But in my proposed scheme, the .mirrors
file would contain only alternative links. The primary links would
still be part of the source array. This is how I envision the



So empty lines separate sources. The order shall follow the order of
the sources listed in the buildscript. The PKGBUILD would still
contain the sources in the format we know. If this .mirrors file does
not exist, the PKGBUILD is still valid and self-contained.

Of course, this is very rudimentary. All it proposes is to fall back
to alternative download links sequentially. If you want things like
parallel downloads from multiple mirrors, that'd require more work.

And I'm not sure the pacman/makepkg devs like hidden files. I
personally use a .contrib file to move over contributor tags when
there are too many. It doesn't become a distraction and it's there for
those who want historical information.
