With the decision to have references to py3k scripts always contain a 
"3", I agree that "make fullinstall" is no longer appropriate.

With r72723 and current py3k, however, there are still some issues.  
Compare ls -l bin from 2.6.2, 3.0.1, and current py3k:

Issues:

1. In py3k bin, there is a "python" binary rather than the symlink that 
was there before.  That appears to be the unstripped binary of the 
interpreter (before it is stripped installed into the fw app bundle). 
Presumably the symlink install used to implicitly remove the binary; now 
an explicit rm is needed?

2. There is still a symlink to python-config.

3. There is no longer *any* 2to3 script, versioned or not. r71936  
(setup.py) is the culprit here (Issue5756, which I'm reopening to ensure 
this issue is examined for all platforms).  With regard to the OSX 
installer, since Tools/scripts isn't installed, there needs to be a 
script of some kind in bin.  As discussed in Issue5756, it should be 
decided how to resolve conflicts between a py2 2to3 and a py3 one.

4. There is no longer any smtpd.py or smtpd3.x.py script/link installed, 
also due to r71936 (setup.py) and to r72723 (Mac/Makefile.in).  I don't 
see this as a huge issue since I doubt that script is used much at all.  
But, at the least, a NEWS/What's New and/or README item about its 
removal in 3.1 is in order.
