+     "@command{frundis} is a tool for compiling documents written in the
+frundis language, a semantic markup language primarily intended for supporting
+authoring of novels, but also well suited for many other kinds of documents.
+The frundis tool can export documents to LaTeX, XHTML 5, EPUB, markdown and
+groff mom.
+
+The language has a focus on simplicity.  It provides a few flexible built-in
+macros with extensible semantics.  It strives to provide good error messages
+and catch typos, while still allowing one to finely control output for a
+specific format when needed.")
