# 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.
