# We want to group several snippets together in the admin menu.
# This is done by defining a SnippetViewSetGroup class that contains a list of
# SnippetViewSet classes.
# When using a SnippetViewSetGroup class to group several SnippetViewSet classes together,
# you only need to register the SnippetViewSetGroup class with Wagtail.
# No need to register the individual SnippetViewSet classes.
#
# See the documentation for SnippetViewSet for more details.
