Because I just did that yesterday :) I have put examples of files at

For example
  cabal2arch --sysinfo=http://dev.archlinux.org/~remy/arch-haskell/hp2011.0
will produce PKGBUILDs which are forced to use library versions
specified in HP2011.0

while cabal2arch --sysinfo=http://dev.archlinux.org/~remy/arch-haskell/default
will use the behaviour we had before.
