[Haskell-cafe] Get "cabal repl" to dump ghc options?

[Carlo Hamalainen]

Hi,

The cabal repl command works out a bunch of GHC options. Is there any
way to dump these options without actually starting the repl?

In particular, things like this:

ghcOptPackageDBs = [ GlobalPackageDB
                   , SpecificPackageDB
\"/home/carlo/foo/.cabal-sandbox/x86_64-linux-ghc-7.6.3-packages.conf.d\",SpecificPackageDB
\"dist/package.conf.inplace\"
                   ]

Basically it would be nice to get the contents of replOpts just before
this bit of code:
