   | zmedico | complete, show a more friendly and informative message.      |

   | 9817    | Make the CHOST visibility check tolerant of missing CHOST    |
   | zmedico | metadata.                                                    |

   | 9819    | Fix "pkg" variable name collisions in depgraph.display().    |
   | zmedico |                                                              |

   | 9821    | Rename variable pkg_cpv to pkg_str.                          |
   | zmedico |                                                              |

   | 9823    | Nest the DepcheckCompositeDB class inside the depgraph class |

   | 9825    | Tweak --buildpkgonly and fakeroot logic so that              |
   | zmedico | --buildpkgonly can be used by a non-root user to build       |
   |         | binary packages with fakeroot.                               |

   | 9827    | Copy group mode bits from $PKGDIR when creating              |
   | zmedico | subdirectories.                                              |
