+opam-version: "2.0"
+maintainer: "contact@ocamlpro.com"
+synopsis: "A simple tool to indent OCaml programs"
+description: """
+Ocp-indent is based on an approximate, tolerant OCaml parser and a simple stack
+machine ; this is much faster and more reliable than using regexps. Presets and
+configuration options available, with the possibility to set them project-wide.
+Supports most common syntax extensions, and extensible for others.
+
+Includes:
+- An indentor program, callable from the command-line or from within editors
+- Bindings for popular editors
+- A library that can be directly used by editor writers, or just for
+  fault-tolerant/approximate parsing.
