-Specifies which major collector to use. Options are `marksweep' for

-`marksweep-par' for parallel Mark&Sweep, `marksweep-fixed' for
-Mark&Sweep with a fixed heap, and `marksweep-fixed-par' for parallel
-Mark&Sweep with a fixed heap. The Mark&Sweep collector is the default.

-\fBmajor-heap-size=\fIsize\fR
-Sets the size of the major heap (not including the large object space)
