Brazil test suite.

The Brazil test suite was derived from the Tcl test suite by CS.
To run the tests, Use something like:

	java -classpath brazil.jar:tcl.jar tcl.lang.Shell all

where "brazil.jar" contains the Brazil system, and "Tcl.jar" contains jacl, the
rewrite of tcl in java.  See the comments in "defs" for more information

Notes:
  - The tests "work" on jdk1.1 and jdk1.2.
  - The tests are totally broken on jdk1.3.  Server.stop() (which is
    only used by the tests) is broken in 1.3.
  - The tests mostly work in jdk1.4.  There are several tests (mostly the
    BSL tests) that make vm specific assumptions.  Hopefully, it's the tests
    and not the code that needs repairing.
  - A copy of "tcl.jar", a modified version of jacl-1.2, is included in
    this directory to make it easier to run the tests (it may be used with
    classes in the sunlabs.brazil.tcl package as well).
