   | 13263   | Add parsing code for --jobs and --load-average.              |
   | zmedico |                                                              |

   | 13264   | Fix typo in comment.                                         |
   | zmedico |                                                              |

   | 13265   | Automatically enable FEATURES=metadata-transfer if it's not  |
   | zmedico | enabled, instead of bailing out.                             |

   | 13266   | Add support for a EGENCACHE_DEFAULT_OPTS variable in         |
   | zmedico | make.conf.                                                   |

   | 13267   | Combine the --rdeps-only and --root-deps options into a      |
   | zmedico | single --root-deps option which takes an optional 'rdeps'    |
   |         | argument.                                                    |

   | 13268   | Clarify docs for --root-deps.                                |
   | zmedico |                                                              |

   | 13269   | Document new prepare and configure commands for EAPI 2.      |
   | zmedico |                                                              |

   | 13270   | Add a man page for egencache(1).                             |
   | zmedico |                                                              |

   | 13271   | Allow --root-deps for ROOT=/, so people can do weird things  |
   | zmedico | like use it with -e to remerge deep runtime deps without     |
   |         | pulling in build-time deps. It's not something we really     |
   |         | want to advertise, but it's good to leave the option open in |
   |         | case it happens to be useful. Thanks to Ned Ludd <solar@g.o> |
   |         | for the suggestion.                                          |

   | 13272   | Remove the ATOMS section and move --update to a new ACTIONS  |
   | zmedico | section.                                                     |

   | 13273   | Bug #264494 - In case the ebuild has enabled set -e during   |
   | zmedico | an ebuild phase, proactively call set +e inside qa_source(), |
   |         | qa_call(), and die().                                        |

   | 13274   | - Add more info to the DESCRIPTION section. - Add a BUGS     |
   | zmedico | section to explain issues related to limitations in the      |
   |         | cache format and its validation mechanism.                   |

   | 13275   | Note that only updates to PORTDIR are currently supported.   |
   | zmedico |                                                              |
