Well, right now I'm finishing overdue homework; first on my list of
demjava fixes is multiple input files.  Then I will look at fixing the
terminal classes parsing problem.  In the meantime, it shouldn't be
that hard to add them manually: replace

    Foo = <ps> PrintStream.

in your .cd file with this in your .beh file:

    Foo {
      (@
	private PrintStream ps;
	public PrintStream get_ps() { return ps; }
	public void set_ps(PrintStream new_ps) { ps = new_ps; }
      @)
    }

Since you can't traverse to terminal classes anyway, this should be
identical, except for not being able to initialize with a constructor.
I do this a lot in demjava.beh (it's also the only way currently to
make static and public data members).
