Upstream changes:
0.18   17 August 2009
        - Changed the Makefile.PL to reduce dependencies not needed by users
          that are not authors.  Bumped the revision and released to clear an
          error with cpan permissions.

0.17   12 August 2009
        - No new functionality.
        - Changed the way we specify dependencies in the Makefile.PL to reduce
          the depth of the dependency chain in cases where we don't need to be
          running the author quality tests.
        - Some documentation tweaks.
