Binary package “libhtml-gentoc-perl” in ubuntu focal

module that generates a Table of Contents for HTML documents

 HTML::GenToc generates anchors and a table of contents for HTML documents.
 Depending on the arguments, it will insert the information it generates, or
 output to a string, a separate file or STDOUT.
 .
 While it defaults to taking H1 and H2 elements as the significant elements to
 put into the table of contents, any tag can be defined as a significant
 element. Also, it doesn't matter if the input HTML code is complete, pure
 HTML, one can input pseudo-html or page-fragments, which makes it suitable
 for using on templates and HTML meta-languages such as WML.
 .
 Also included in the distrubution is hypertoc, a script which uses the module
 so that one can process files on the command-line in a user-friendly manner.
