+     "This package converts LaTeX to HTML by using LaTeX to process the user's
+document and generate HTML tags.  External utility programs are only used for
+the final conversion of text and images.  Math may be represented by SVG files
+or MathJax.  Hundreds of LaTeX packages are supported, and their load order is
+automatically verified.  Documents may be produced by LaTeX, LuaLaTeX,
+XeLaTeX, and by several CJK engines, classes, and packages.  A texlua script
+automates compilation, index, glossary, and batch image processing, and also
+supports latexmk.  Configuration is semi-automatic at the first manual
+compile.  Support files are self-generated.  Print and HTML versions of each
+document may coexist.  Assistance is provided for HTML import into EPUB
+conversion software and word processors.")
