"""Script to help update a tree packager installation to the current
version.  The script updates the information stored in the filesystem
for the individual revisions in the following ways:

 - Rename the build log from build.log to log/build_log.txt

 - Rename the build log from build_log.txt to log/build_log.txt

 - Rename the directory name of the revision from <revision>-1 to <revision>-0

   The second number is now the revision of the packaging rules if
   they're managed by SVN and always 0 for manual management of the
   rules.
