If foobar-0.2.tar.gz contains a tarball created by "cabal sdist", then I
can install it via
$ cabal install foobar-0.2.tar.gz
In this case, cabal-install unpacks the archive, configures, builds and
installs the package. It would be neat to run the pvp check in the same way:
$ cabal install --haskellsuite -w check-pvp-compiler foobar-0.2.tar.gz
However, this requires that check-pvp-compiler gets the path to the
package description as parameter and does not try to load it from the
