Build roundtripping executables
Using the API Annotations available from GHC 7.10.2, this library provides a means to round trip any code that can be compiled by GHC, currently excluding lhs files.
It does this with a phased approach
Delta - converts GHC API Annotations into relative offsets, indexed by SrcSpan
Transform - functions to facilitate changes to the AST, adjusting the annotations generated in the Delta phase to suit the changes.
Print - converts an AST and its annotations to properly formatted source text.
Note: requires GHC 7.10.2 or later
