BTW.  Opossum is used as a configuration language for Gamora, another
project.  Its used as the default text presentation for the Lightweight
Distributed Objects protocol (as opposed to LDO-Binary, which I mentioned
earlier).  

Its acronym stands loosely for Object Pickler/ String and Stream
Marshaller.

One of the nice things it was good for was specifying complex arguments to
functions that knew only about Strings, for example:

java org.gamora.Foo "{ttl=30, host=casbah.org, port=3228, keys=[salt,sugar, 
pepper, paprika]}"

The app would then run that through opossum and would have a preparsed
setup dictionary.
