+This class works like a 'stage3'.  A stage2 tarball is unpacked, but instead
+of building a stage3, it emerges a 'system' into another directory
+inside the 'stage2' system.  This way we do not have to emerge gcc/portage
+into the staged system.
+
+It sounds real complicated but basically it's a it runs
+ROOT=/tmp/submerge emerge --blahblah foo bar
