-# Ikiwiki setup files are perl files that 'use IkiWiki::Setup::foo',
-# passing it some sort of configuration data.
-#
-# There can be multiple modules, with different configuration styles.
-# The setup modules each convert the data into the hashes used by ikiwiki
-# internally (if it's not already in that format), and store it in
-# IkiWiki::Setup::$raw_setup, to pass it back to this module.
+# Ikiwiki setup files can be perl files that 'use IkiWiki::Setup::foo',
+# passing it some sort of configuration data. Or, they can contain
+# the module name at the top, without the 'use', and the whole file is
+# then fed into that module.
