   | 10710   | Use optparse instead of getopt.                              |
   | zmedico |                                                              |

   | 10711   | Add a help string for --debug.                               |
   | zmedico |                                                              |

   | 10712   | Bug #225285 - Add a --skip-manifest option that disables all |
   | zmedico | interaction with the manifest.                               |

   | 10713   | Bug #225285 - Add support for persistent options stored in   |
   | zmedico | the EBUILD_DEFAULT_OPTS environment variable (similar to     |
   |         | {EMERGE,QUICKPKG}_DEFAULT_OPTS).                             |

   | 10714   | Add an exemption for x-modular in the "inherit.autotools"    |
   | zmedico | check. Thanks to remi` for reporting.                        |

   | 10715   | As suggested by remi`, make the 'inherit.autotools' check    |
   | zmedico | only ebuilds that inherit the autotools eclass directly      |
   |         | (rather than indirectly through an eclass such as apache-2   |
   |         | or x-modular).                                               |
