Hello all,

Unfortunately, today is the day that we are moving into our new place.
 Thus, I will be mostly offline until early next week unless I can
sneak out to a coffee house some night.  Fernando can help make any
decisions about how to proceed with the merges.  Thanks again everyone
for helping out.
