+# Modules are expected to have the following attributes.
+# 1. A required 'handle' method which takes the following params.
+# a) The name will not be this files name, but instead
+# the name specified in configuration (which is the name
+# which will be used to find this module).
+# b) A configuration object that is the result of the merging
+# of cloud configs configuration with legacy configuration
+# as well as any datasource provided configuration
+# c) A cloud object that can be used to access various
+# datasource and paths for the given distro and data provided
+# by the various datasource instance types.
+# d) A argument list that may or may not be empty to this module.
+# Typically those are from module configuration where the module
+# is defined with some extra configuration that will eventually
+# be translated from yaml into arguments to this module.
+# 2. A optional 'frequency' that defines how often this module should be ran.
+# Typically one of PER_INSTANCE, PER_ALWAYS, PER_ONCE. If not
+# provided PER_INSTANCE will be assumed.
+# See settings.py for these constants.
+# 3. A optional 'distros' array/set/tuple that defines the known distros
+# this module will work with (if not all of them). This is used to write
+# a warning out if a module is being ran on a untested distribution for
+# informational purposes. If non existent all distros are assumed and
+# no warning occurs.
