Also disables all HTML/CSS -C<style> attributes that are output by default (to avoid conflicts). - -=item flush - - --flush - -Flushes the item and directory caches. - -=item header - - --header - --noheader - -Creates header and footer blocks containing the text of the C<NAME> -section. By default, no headers are generated. - -=item help - - --help - -Displays the usage message. - -=item hiddendirs - - --hiddendirs - --nohiddendirs - -Include hidden directories in the search for POD's in podpath if recurse -is set. -The default is not to traverse any directory whose name begins with C<.>. -See L</"podpath"> and L</"recurse">. - -[This option is for backward compatibility only. -It's hard to imagine that one would usefully create a module with a -name component beginning with C<.>.] - -=item htmldir - - --htmldir=name - -Sets the directory in which the resulting HTML file is placed.

This is the default -behaviour. - -=item infile - - --infile=name - -Specify the pod file to convert. Input is taken from STDIN if no -infile is specified. - -=item libpods - - --libpods=name:...:name - -List of page names (eg, "perlfunc") which contain linkable C<=item>s. - -=item netscape - - --netscape - --nonetscape - -B<Deprecated>, has no effect. For backwards compatibility only. - -=item outfile - - --outfile=name - -Specify the HTML file to create.

These messages -will be displayed by default. But this is not the same as C<verbose> -mode. - -=item recurse - - --recurse - --norecurse - -Recurse into subdirectories specified in podpath (default behaviour). - -=item title - - --title=title - -Specify the title of the resulting HTML file. - -=item verbose - - --verbose - --noverbose - -Display progress messages. By default, they won't be displayed. - -=back - -=head2 htmlify - - htmlify($heading); - -Converts a pod section specification to a suitable section specification -for HTML.
