"""Usage: treepkgbuilder COMMAND [options]

Manage the pbuilder environment for a tree packager installation.  The
pbuilder settings are taken from the configuration file, either the
default treepkg.cfg or the one given with the --config-file option.
Also, this script assumes that there is only one pbuilder setting for
all packagers.  Use treepkgbuilder COMMAND --help for more details about
the commands.
