-- Output template parameter functions
-------------------------------------------------------------------------------

-- The results of these functions are substituted into parameters in the
-- output template. The parameters look like ${PARAMETER_NAME}. Trying to use
-- a parameter that doesn't have a function defined here will result in an
-- error.

-- the following fields:
-- * errors - a table of formatted error messages that were found when
--     processing the input.
-- * args - the table of arguments supplied by the user.
-- * articles - an array of the article names found in the arguments.
-- * authors - an array of the expanders/creators/writers/authors found in the
--     arguments.
-- * revisionUser - the user that last edited the page. As this module is only
--     substituted, this is always the current user.
-- * alts - an array of the ALT hooks found in the arguments.
-- * title - the mw.title object for the current page.

-- Functions returning false or nil will be treated as outputting the empty
-- string "".
