+ (description "OCaml is written in OCaml. Its sources contain a pre-compiled
+bytecode version of @command{ocamlc} and @command{ocamllex} that are used to
+build the next version of the compiler. Camlboot implements a bootstrap for
+the OCaml compiler and provides a bootstrapped equivalent to these files.
+
+It contains a compiler for a small subset of OCaml written in Guile Scheme,
+an interpreter for OCaml written in that subset and a manually-written lexer
+for OCaml. These elements eliminate the need for the binary bootstrap in
+OCaml and can effectively bootstrap OCaml 4.07.
+
+This package produces a native @command{ocamlc} and a bytecode @command{ocamllex}.")
