+opam-version: "2.0"
+synopsis: "A Markdown frontend in pure OCaml"
+description: """
+This Markdown library is implemented using only pure OCaml (including
+I/O operations provided by the standard OCaml compiler distribution).
+OMD is meant to be as faithful as possible to the original Markdown.
+Additionally, OMD implements a few Github markdown features, an
+extension mechanism, and some other features. Note that the opam
+package installs both the OMD library and the command line tool `omd`."""
