[arch-haskell] How to update packages in extra?

[Peter Simons]

Hi,

the PKGBUILD files in "extra" have been generated with ancient versions
of cabal2arch, like 0.4.1, and because of that they lack features such
as the generation of Haddock reference documentation. Is there any way
for us to update those files? Who has the ability to do that?

Take care,
Peter
