.. index:: single: Configurator; IConfigurator
A configurator is an object which configures several components of Buildbot in a coherent manner. This can be used to implement higher level configuration tools.
.. method:: configure(config_dict)
Alter the Buildbot ``config_dict``, as defined in master.cfg.
Like master.cfg, this is run out of the main reactor thread, so this can block, but it can't
call most Buildbot facilities.
