Yep. Here's what you'll need to do to prepare the code itself:

• Make sure the boilerplate is parseable by package.el. If in doubt, enable auto-insert-mode and let it help you create a fresh hare.el, then paste the code into it. Test with M-: (package-buffer-info).
• Use a consistent prefix for all identifiers. So ghc-hare-command => hare-ghc-command, erlang-xemacs-p => hare-erlang-xemacs-p, refac-result => hare-refac-result etc.
• Rename read-char-spec.el to hare-read-char-spec.el, or inline it in hare.el
• Move your provide form to the bottom, before the ;;; hare.el ends here comment which auto-insert-mode will add
• Add a ;; Package-Requires: header to specify a dependency on haskell-mode, e.g. ;; Package-Requires ((haskell-mode "13.10")).
• Remove all the messy commented-out code referring to erlang, distel etc.

Regarding the way the code works, the hare-init code is a bit hacky, since it directly modifies haskell-mode-map. What you want instead is to define a minor mode hare-mode, and add the keybindings to the resulting hare-mode-map. Then users can just enable hare-mode in their haskell-mode-hook.

Hope that helps.
