+# ocaml-bin-prot
+
+[`Bin_prot`](https://github.com/janestreet/bin_prot) contains functionality
+for reading and writing OCaml values in a type-safe binary protocol.  These
+functions are extremely efficient and provide users with a convenient and safe
+way of performing I/O on any extensionally defined data type.  This means that
+functions, objects, and values whose type is bound through a polymorphic
+record field are not supported, but everything else is.
+
+As of now, there is no support for cyclic or shared values.  Cyclic values
+will lead to non-termination whereas shared values, besides requiring
+significantly more space when encoded, may lead to a substantial increase in
+memory footprint when they are read back in.
