   | 12059   | Document "I" which represents PROPERTIES=interactive in the  |
   | zmedico | merge list display.                                          |

   | 12061   | Use a table to organize the key of merge list display codes  |
   | zmedico | for the --pretend option.                                    |

   | 12063   | Use a table to organize the key of USE flag symbols for the  |
   | zmedico | --verbose option.                                            |

   | 12065   | Make emerge detect an invalid profile an bail out for        |
   | zmedico | anything except --help, --info, --sync, and --version        |
   |         | actions. When bailing out, suggest to revert back to the     |
   |         | previous profile configuration advise the user which actions |
   |         | are allowed with an invalid profile.                         |

   | 12066   | Inside profile_check(), call validate_ebuild_environment()   |
   | zmedico | to generate some extra profile warnings when appropriate.    |

   | 12068   | Add support for parsing EAPI labels in contained in 'eapi'   |
   | zmedico | files in the profiles, and bail out if the profile contains  |
   |         | an unsupported EAPI value in any one of it's directories. We |
   |         | don't necessarily have to use this but at least it gives us  |
   |         | some way to make emerge bail out early if a profile contains |
   |         | unsupported EAPI features.                                   |

   | 12070   | Document the 'eapi' profile file.                            |
   | zmedico |                                                              |

   | 12072   | Fix typo in --help.                                          |
   | zmedico |                                                              |

   | 12077   | Add one newline, to wrap the "Global Updates" key to less    |
   | zmedico | than 80 columns.                                             |

   | 12079   | Also add 2 spaces after newline, for alignment.              |
   | zmedico |                                                              |

   | 12081   | Use tar options to make files owned in release tarballs      |
   | zmedico | owned by portage:portage instead of the current user.        |

   | 12086   | Remove world and system targets for emerge --help since it   |
   | zmedico | no longer works now that they are sets rather than actions.  |
