installing non-haskell binaries with cabal

   I'd still be happy if cabal better supported heterogeneous projects, 
where some parts are written in another language. Count it as my feature 
request - seems to be be quite easy as far as executable installation is 
concerned.
   There are many reasons to write some utilities in another language, like
  * legacy code
  * a two-liner shell script is small, where an equivalent compiled
    haskell code may be hundreds of kbs (looks like cabal doesn't allow
    to install haskell scripts, only compiled code)
  * my editor does syntax highlighting for pure shell scripts but not for
    shell scripts wrapped in haskell
  * love for pipes, subshells, perl regular expressions, etc.

   If you want an example, look at ghc: it comes with perl scripts.

Cheers,
