mergeModules : generate a full Haskell src file, give a .hs config file, and a stub to take default syntax and decls from. Mostly we just ensure they don't do anything bad, and that the names are correct for the module.
Transformations:
. Take src location pragmas from the conf file (1st file) . Use the template's (2nd argument) module name . Only use export list from template (2nd arg) . Merge top-level decls . need to force the type of the plugin to match the stub, overwriting any type they supply.
pretty print haskell src
doesn't handle operators with # at the end. i.e. unsafeCoerce#

Parsing option pragmas. This is not a type checker. If the user supplies bogus options, they'll get slightly mystical error messages. Also, we want to handle -package options, and other static flags. This is more than GHC. GHC user's guide : OPTIONS pragmas are only looked for at the top of your source
files, up to the first (non-literate,non-empty) line not
containing OPTIONS. Multiple OPTIONS pragmas are recognised.
