-% Forces a program compiled for generational GC to use two-space copying
-% collection. The two-space collector may outperform the generational
-% collector for programs which have a very low heap residency. It can
-% also be used to generate a statistics file from which a basic heap

-% still be executed (of course none will actually happen). This
