-typecheck true  turns on type checking of the CPS IL after every
simplification pass.  ("true" was the default behavior with a G0 compiler
and "false" was the default behavior with a G1 compiler.  "false" is now
the default in both, but you know have the option of turning it on in a G1
compiler.)

-keep dot  keeps an interprocedural control flow graph for the whole
program and intraprocdural control flow graphs for each top-level CPS
function in the graphviz .dot format.  Like the one Steve sent out
earlier.
