Of course this is a great thing to have, but it should be noted that 
this massive file of "glue" depends heavily on VW's 
"ExternalInterface" facility, which permits an in-smalltalk 
specification of calls to an external universe.

Although there is a means by which this can be accomplished in part 
by generating a named plugin, there is really  no comparable facility 
in Squeak at this time.  (Some of us are working on it, however . . .)
