+     "Skribilo is a free document production tool that takes a structured
+document representation as its input and renders that document in a variety of
+output formats: HTML and Info for on-line browsing, and Lout and LaTeX for
+high-quality hard copies.
+
+The input document can use Skribilo's markup language to provide information
+about the document's structure, which is similar to HTML or LaTeX and does not
+require expertise. Alternatively, it can use a simpler, “markup-less” format
+that borrows from Emacs' outline mode and from other conventions used in
+emails, Usenet and text.
+
+Lastly, Skribilo provides Guile Scheme APIs.")
