   | 9451    | Make --prune and --depclean operate with missing             |
   | zmedico | dependencies when only asked to remove specific packages     |
   |         | since it's relatively safe in this case.                     |

   | 9452    | Convert PackageIndex.packages from a dict to a list so that  |
   | zmedico | in the future it will be possible to support multiple        |
   |         | packages with the same cpv.                                  |

   | 9453    | Make readpkgindex() and writepkgindex() private methods of   |
   | zmedico | PackageIndex.                                                |

   | 9455    | add some status messages, try to copy the tarball into       |
   | genone  | DISTDIR, use getopt for option parsing                       |

   | 9456    | Fix var_assign_re to recognize a call to the 'declare'       |
   | zmedico | builtin even when no options are given.                      |

   | 9457    | When all available ebuilds are masked, avoid producing       |
   | zmedico | warning message when the package does not need to be         |
   |         | reinstalled and the installed version is not masked.         |

   | 9458    | Bug #212882 - Fix lockfile() to handle errno.EACCES raised   |
   | zmedico | from the fcntl call since the spec says that it's equivalent |
   |         | to EAGAIN and it appears that CIFS returns EACCES in this    |
   |         | case.                                                        |

   | 9459    | - news bugfix from ferringb                                  |
   | solar   |                                                              |

   | 9460    | Make strip_empty() return a nedw list instead of working     |
   | zmedico | in-place. Thanks to René Neumann <rene.neumann@necoro.net>  |
   |         | for the suggestion.                                          |
