This library aims to make it possible for objects created by a runtime for one dynamic language to be passed to and manipulated by a different dynamic language, running within the same jvm. more generally, it aims to provide a facility where an arbitrary system (usually a language runtime) can intuitively manipulate any arbitrary object model built atop of java objects (usually the native object model of some other language).

basically, it provides a unified mechanism that all dynamic languages on the jvm can use to inter-operably manipulate their own objects as well as objects from any other language that also uses this mechanism.
