-      Caml on the Web (COW) is a set of parsers and syntax extensions to let you manipulate HTML, CSS, XML, JSON and Markdown directly from OCaml code.
+      Writing web-applications requires a lot of skills: HTML, XML, JSON and
+      Markdown, to name but a few! This library provides OCaml combinators
+      for these web formats.
