This will generate documentation (e.g. Unix man pages and HTML documents) for any installable items under blib/ that contain POD. If there are no bindoc or libdoc installation targets defined (as will be the case on systems that don't support Unix manpages) no action is taken for manpages. If there are no binhtml or libhtml installation targets defined no action is taken for HTML documents.
