   | 6711    | Don't complain when $FILESDIR is missing unless manifest1    |
   | zmedico | compatibility is enabled.                                    |

   | 6716    | Fix it so repoman still does QA when $FILESDIR doesn't       |
   | zmedico | exist.                                                       |

   | 6718    | Add an optional PATH attribute to the Packages index in      |
   | zmedico | order to indicate the relative path of the package within    |
   |         | the repository. In the future this will allow storage of     |
   |         | more than one package per cpv but for now it's just use to   |
   |         | indicate if a package is stored in the old-style All/        |
   |         | directory (instead of the category directory).               |
