		This library provides a quick-and-dirty (but often effective)
		method for extending Haskell&#39;s syntax using a custom
		preprocessor.  It parses Haskell into a bare-bones AST with just
		enough knowledge of the syntax to preserve nesting, and then
		allows transformations on the AST.
		
		See the package ixdopp
		(&lt;http://hackage.haskell.org/cgi-bin/hackage-scripts/package/ixdopp&gt;)
		for an example of how to do this.
