   | 6697    | Replace deprecated binarytree.remotepkgs usage with          |
   | zmedico | binarytree._remotepkgs since the former is vulnerable to     |
   |         | collisions in the tbz2 filename.                             |
   |---------+--------------------------------------------------------------|
   | 6698    | Make dep_zapdeps() pull SLOT from the correct dbapi instance |
   | zmedico | when it falls back to the vdb.                               |
   |---------+--------------------------------------------------------------|
   | 6699    | Raise a KeyError from bindbapi.aux_get() when appropriate.   |
   | zmedico |                                                              |
   |---------+--------------------------------------------------------------|
   | 6704    | Fix typo.                                                    |
   | zmedico |                                                              |
   |---------+--------------------------------------------------------------|
   | 6705    | Add some additional variables to the Packages header.        |
   | zmedico |                                                              |
   |---------+--------------------------------------------------------------|
   | 6706    | For bug #149397, raise an InvalidDependString exception if a |
   | zmedico | USE has no basename.                                         |
   |---------+--------------------------------------------------------------|
   | 6707    | Don't repeatedly invoke the depend phase for ebuilds that    |
   | zmedico | are already known to be broken.                              |
   |---------+--------------------------------------------------------------|
   | 6708    | Instead of calling sys.exit() when aux_get() fails inside    |
   | zmedico | getfetchlist(), convert the KeyError to an                   |
   |         | InvalidDependString exception since callers already handle   |
   |         | it.                                                          |
   |---------+--------------------------------------------------------------|
   | 6709    | Add --getbinpkg digest verification.                         |
   | zmedico |                                                              |
