webhelp.default.topic — The name of the file to which the start file in the webhelp base directory redirects
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.
