After setting up a Hudson continuous build for the network package
I've filed http://hackage.haskell.org/trac/hackage/ticket/787

The feature request is pretty straightforward; allow template
placeholders in --test-option. The problem is that the PathTemplate
type seems designed for directory paths (no surprise their I guess).
If I want to support template placeholders in a flag argument that's
not necessarily a path, should I still use it?

Aside: I think this feature will give us much bang-for-the-buck. It,
together with better HPC support, would allow us to fully integrate
building of Cabal package with main stream continuous build systems,
such as Hudson. We could even add a Cabal plugin for Hudson that would
allow anyone to point Hudson at a repo containing a Cabal package and
have it

 * configure and build the package,
 * run the tests,
 * provide detailed test run feedback,
 * show test coverage, and
 * build haddocks.

We're almost there, have a look at
