Maybe here, or somewhere, I wonder about inserting:
Since the Free Software Foundation holds the sole copyright on GNU
Automake, it will be necessary for any significant contributor,
whether individual or corporate, to sign a disclaimer or assignment of
copyright before contributions can be accepted. Please confirm that
this is acceptable.
I still worry that this is going to be a stopper. Or at least a big
delayer. The last thing I want is for us to go through this whole
process and then neighborhoodie "can't" sign the assignment. Or for them
to start posting changes but I can't install them because the assignment
hasn't happened.
