    Revision as of 03:13, 21 March 2014 by m>Mr. Stradivarius (use a dedicated config page - Module:Namespace detect/config - for configuration data, and try and reduce unnecessary table lookups in the getParamMappings function)

    Documentation for this module may be created at Module:Namespace detect/data/doc
