fetchurl {
url = http://heanet.dl.sourceforge.net/sourceforge/zapping/zapping-0.9.6.tar.bz2;
md5 = "8306775c6a11de4d72345b5eee970ea6";
};
you can write
fetchurl {
url = mirror://sourceforge/zapping/zapping-0.9.6.tar.bz2;
md5 = "8306775c6a11de4d72345b5eee970ea6";
};
which causes fetchurl to try the SourceForge mirrors listed in the
`sourceforge' attribute in build-support/fetchurl/mirrors.nix.
(They're currently tried in sequence, and the lists of mirrors are
not configurable yet.)
The syntax for mirror URLs is mirror://site/path/to/file, where
`site' is currently one of `sourceforge', `gnu' (mirrors of
ftp://ftp.gnu.org/pub/gnu) and `kernel' (mirrors of
http://www.all.kernel.org/pub/).
