 I'm trying to keep the source of multiple packages in a single source
 repository. Unfortunately, I cannot maintain a .cabal file per package,
 because some commands invoke function defaultPackageDesc unconditionally.

 I tried using {{{defaultMainNoRead}}} instead of {{{defaultMain}}}
 and passing the desired package name through the environment. This
 solution doesn't work at all in 1.6.0.3. It works only partially in HEAD:
 {{{Setup configure}}} and {{{Setup build}}} work but {{{Setup sdist}}}
 does not because it ignores the {{{readDesc}}} field and invokes
 {{{defaultPackageDesc}}} unconditionally.

 Would it be possible to add a field to {{{UserHooks}}} which would specify
 the .cabal filename to use? Then {{{defaultPackageDesc}}} should be always
 called through this field, never directly, and could thus be consistently
 overridden.
