devel/ocaml-camljava 0.5 DragonFly

This is a very preliminary release of CamlJava, an OCaml/Java interface based on the following schema:

     Caml/C interface       JNI (Java Native Interface)

Caml <------------------> C <-----------------------------> Java

Currently, CamlJava provides a low-level, weakly-typed OCaml interface very similar to the JNI. Java object references are mapped to an abstract type, and various JNI-like operations are provided to allow Java method invocation, field access, and more. A basic callback facility (allowing Java code to invoke methods on Caml objects) is also provided, although some stub Java code must be written by hand.

In the future, a higher-level, strongly-typed interface will be provided, whereas Java classes are mapped directly to Caml classes. This raises fairly delicate type mapping issues, though, so don't hold your breath.
