Here you go.
Example:  ./moo -l mymoo.log mymoo.db mymoo.db.new 4283
Um... i believe it works in emergency mode too, though my testing wasn't 
as robust in that area.

No warranty is expressed or implied by this hunk of code.  If it works 
for you, great.  If not, well, ask me real nice, and we'll talk.
