Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070516030658] 
[Add an operator<< for aptitude resolver-versions.
Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070310182027] 
[Add support for dumping order information with solutions.
Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070310182155] 
[Add macros/AssertionError constructors that allow you to attach more information to an assertion failure.
Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070310182216] 
[Change how we apply bolding to literal elements so that it works with the new Docbook templates (Closes: #415468, #416232).
Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070329021906] 
[Add DPKG_NO_TSTP to the environment when configuring packages after something failed to install. (Closes: #367052)
Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070422161245
 Apparently this is necessary to keep things sane.  It would be nice if I
 could call on apt to do this, but apt doesn't expose a wrapper around
 "dpkg --configure -a".

[Cleanly handle exceptions thrown by the dependency resolver.
Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070422190408
 Previously, the program would unceremoniously abort when the resolver
 tossed an exception; now exceptions are caught, propagated to the main
 loop, and reported to the user.  It's even possible to keep searching
 for more solutions, although some solutions (the ones on the branch
 that blew up) are probably toast.

[Don't crash when generating a revdep-count column for certain virtual packages. (Closes: #420405)
Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070422193031] 
[Add a routine that will run some sanity-checks on a dependency universe model; it doesn't guarantee that the universe matches reality, but it does empirically check that the graph connectivity is as expected (e.g., that all reachable dependencies are in the global dependency list).
Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070509143611] 
[Invoke the sanity checker when running a test on the dummy universe.
Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070509143824] 
[Add a command-line action that runs the sanity-checker on the universe in its initial state.
Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070509143913] 
[Fix inconsistencies in aptitude's model of the dependency universe (Closes: #420358, #420381, #420407).
Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070514153804] 
[Add operator<< for dummy-universe versions.
Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070310182048] [Add a changelog entry for 0.4.4-5~2.
Daniel Burrows <Daniel_Burrows@alumni.brown.edu>**20070520213007] 
[Don't assert that percentages are sane; instead, be robust by clamping them to [0, 100].  (Closes: #425145)
