Hey there! :) Sorry for answering before vmiklos :)) The idea is good.
As i know (correct me if i'm wrong) now descriptions are handled via %
DESC% in pacman's code. To PKGBUILD it isn't hard to implement this. But
in pacman code there is much more complicated.

As we know that if you follow the way pkgdesc="something" and
pkgdesc_XX_yy="" scheme then we got troubles in %DESC% field.

I don't know the right codepart for %DESC% processing. But i see two

1. need to extend %DESC% , %DESC_XX_YY% , etc..etc..

2. need to extend %DESC% with something like this:

en - english and core description (eqivalent to simple pkgdesc="")
XX_YY - some other language description (eqivalent to pkgdesc_XX_YY="")

As in the codepart we need to catch the actual locale (this is easy) .

1 situation: If we got the actual locale example: hu_HU then in
codeparsing we need to "search" for %DESC_hu_HU% part instead of %DESC%

2 situation: If we got the actual locale: example hu_HU then we need a
rewrited parser code which somehow (not want to write technical stuff
here now) which pulls out from %DESC% the line stars with hu_HU .

At sit 1. and sit. 2 we need to do a check if a description is available
in that locale what we are running example: xx_YY if that not founded
then we roll back to default english style. This is easly possible and
coded too.

We need to think whats better. the %DESC_XX_YY% or the

en - somedesc
XX_YY - somethingdesc in other language

I prefer the second way because we don't need to store unusefull
newlines. So the filesize not growns too big.

If this is a good idea i will work on it and code it into pacman

If not a good idea i will code it too. :P Maybe just wont be commited
(like my libarchive and progressbar patches ...).

Waiting for comments :)
