+     "This package provides a converter from TeX and LaTeX to SGML-based
+formats such as (X)HTML, MathML, OpenDocument, and Docbook, providing
+a configurable (La)TeX-based authoring system for hypertext.  TeX4ht does not
+independently parse (La)TeX source (so it avoids the difficulties encountered
+by many other converters, arising from the irregularity of (La)TeX syntax).
+Instead, TeX4ht uses (La)TeX itself (with myriad macro modifications) to
+produce a helper DVI file that it can then process.  This technique allows
+TeX4ht to approach the robustness characteristic of restricted-syntax systems
+such as @code{gellmu}.")
