-# enabled_features - used to specify tests for features that are not

-# ObjectStorageFixture.required_features will requilred all
-# features in the tag to be listed here in order to be run.
-# in addition to listing the features here, '__ALL__', '__NONE__' and
-# '__ASK__' can be provided to run all features tests, run no features

+# Tests can be tagged with a decorator as follows:
+#     @ObjectStorageFixture.required_features('feature1', 'feature2')
+# These tagged tests, will only be run if all of the features listed have
+# been added to the features key.  If use_swift_info is true, features will
+# be pulled from the swift info and added to the features defined here.
+# The features are defined by adding them to a whitespace separated list
+# as follows:
+#     features=foo bar ...
+# by defaut, no features are added.

+
+# In addition to setting the features, you can also exclude features from
+# being reported.  If for example you have the following:
+#     features=foo bar
+#     excluded_features=foo
+# This will have the same efect as the following:
+#     features=bar
+# The advantage of this is if there are features returned from the swift info
+# call that you do not want to run regularly.  The following special values
+# can also be set:
+#   __ALL__  - runs all tests tagged with required_features, regardless of
+#              the features listed in the decorator.
+#   __NONE__ - runs no tests tagged with required_features, regardless of
+#              the features listed in the decorator.
