[Nix-dev] is the default builder able to deal with fetchurl being given a tar.xz archive?

[Tony White]

Hi,
I've noticed a few projects like gnuzilla, etc are offering out tar.xz
archives :

http://ftp.gnu.org/gnu/gnuzilla/3.5.1/

 icecat-3.5.1.tar.bz2 = 41M
 icecat-3.5.1.tar.xz   = 34M

If pulling lots of archives, that's going to be quite a big bandwidth
saving. 7M seems quite attractive. :)

I've read some benchmarks and opinions searching google and xz
certainly seems like it might be adopted quite widely.
So what I was wondering was, would I be able to use a tar.xz in an
expression and the default builder takes care of extracting it?

Thanks,

Tony
