The only comment I have at this point is that this is a huge update to
a somewhat fragile tool.  It'll need a lot of testing before it should
be comitted this way;  not sure how many ports use this rather than gm4
or if they could be switched over after that.  I'd at least ask portmgr
for an exp run.
