-%description
-LaTeX2HTML replicates the basic structure of a LaTeX document as a set of
-interconnected HTML files which can be explored using automatically generated
-navigation panels. The cross-references, citations, footnotes, the table of
-contents and the lists of figures and tables, are also translated into hypertext
-links. Formatting information which has equivalent tags in HTML (lists, quotes,
-paragraph breaks, type styles, etc.) is also converted appropriately. The
-remaining heavily formatted items such as mathematical equations, pictures or
-tables are converted to images which are placed automatically at the correct
-positions in the final HTML document.
