 description:
 """
+Patoline is a collection of typesetting libraries designed to be combined into
+a variety of possible applications. Its primary goal is not to offer the
+definitive answer to all typesetting problems, but rather to write the painful
+and boring parts of the job, so that interesting tools could be written
+easily. Obviously, a related (but much smaller) project is the Patoline
+compiler, which compiles a mixed Wiki/LaTeX/Ocaml syntax into a variety of
+output formats, including traditional PDF files, but also web servers that
+deliver dynamic contents.
