--- Get an interactive shell with the right packages to load

--- To use:
--- runghc Interact.hs
--- then,
--- :l Text/Pandoc.hs
--- (or whichever package you like)
-
--- You must have first done a 'cabal configure' or 'cabal install'
-
--- Note:  Interact.hs doesn't work with Cabal >= 1.18.  I recommend
--- using cabal sandboxes and the new 'cabal repl' command if you are
--- using a recent version.
