webhelp.default.topic string webhelp.default.topic The name of the file to which the start file in the webhelp base directory redirects index.html Currently webhelp creates a base directory and puts the output files in a content subdirectory. It creates a file in the base directory that redirects to a configured file in the content directory. The webhelp.default.topic parameter lets you configure the name of the file that is redirected to. This parameter will be removed from a future version of webhelp along with the content directory.
