/mozregression/fetch_configs.py

"""
This module defines the configuration needed for nightly and integration
fetching for each application. This configuration is a base block
for everything done in mozregression since it holds information
about how to get information about builds for a given application.

The public entry point in there is :func:`create_config`, which
creates an returns a fetch configuration. the configuration will
be an instance of :class:`CommonConfig`, possibly using the mixins
:class:`NightlyConfigMixin` and/or :class:`IntegrationConfigMixin`.
<
Example to create a configuration for firefox on linux 64: ::

  fetch_config = create_config('firefox', 'linux', 64)

You can also use the variable *REGISTRY* defined in this module to get a
list of application names that can be used to build a configuration. This is
an instance of :class:`ClassRegistry`. Example: ::

  print REGISTRY.names()
