The Mini-Trace Package:
-----------------------

The following 4 functions (all FEXPRs) are defined:
 (they each redefine the functions, saving an old definition)

TR ([F:id])             Cause TRACE message to be printed on entry to
                         and exit from calls to the functions F1 ... Fn.
UNTR ([F:id])           Restore original definitions

BR ([F:id])             Cause BREAK on entry and on exit from functions,
                         permitting arguments and results to be examined
                         and modified.
UNBR ([F:id])           Restore original definitions of the functions
			 F1 ... Fn.

Fluids:
-------
TrSpace!*                Controls indentation, may need to be reset to 0
                         in "funny" cases.
!*NoTrArgs               Set to T to suppress printing of arguments of
                         traced functions.
