   | 6630    | In the econf die message, don't mention bugs.gentoo.org      |
   | zmedico | specifically.                                                |

   | 6631    | xmlint can produce garbage output even on success, so only   |
   | zmedico | dump the ouput when it fails. See bug #179008.               |

   | 6633    | Create the Packages index whether or not $PKGDIR/All/ exists |
   | zmedico | so that improved binarytree.populate() performance will be   |
   |         | available in either case. When dealing with packages in      |
   |         | $PKGDIR/All/, it's assumed that the file name, size, and     |
   |         | timestamp are enough information to avoid reading the xpak   |
   |         | data.                                                        |
