 That seems to be working well for most files, but those listed in the
 data-files field of the Cabal package are still installed with permission
 rw for the owner (root), zero permission for group and others.

 I can work around this by doing
 {{{
 chmod -Rf g+rX,o+rX .
 }}}
 in the source directory where I am developing the package, __before__
 building the source tarballs for release.  Of course, likewise the
 installer can do so after unpacking the tarballs, or even after the files
 are installed.

 Seems like this might be a big nuisance for projects using darcs with
 multiple developers, since darcs does not preserve file permissions.
