Very cool. I just ran this on our code base:

Code stats           Tweak       Croquet
Nr of packages:         14            17
Nr of categories        53            26
Nr of classes:         297           241
Nr of methods:        6168          6476
lines of code:       36919         49063
Avg methods/class:    20.7          26.8
Avg lines/method:      5.9           7.5
	
Nr of test methods:      6           150
% of commented methods: 50            53
% of commented classes: 59            92

(I'll ask if I can share the numbers on the Qwaq packages as well). One 
relevant note is that I don't have the Tweak test packages loaded which 
explains the absence of tests. Other than that it looks as if there's 
virtually no difference in terms of average length of methods (Tweak is 
a little lower probably because of auto-generated accessors) but it's 
amazing that the average length of Croquet (and Qwaq) methods is 
virtually identical to the average length of Aida and Seaside methods :-)

One thing that was interesting to me was that when I ran the method 
distribution code I found that we have a significant number of classes 
with more than 50 methods (in the 10% range). In your comparison, there 
is nothing listed beyond 50 methods/class. Are there no classes with 
more methods in any of the frameworks, or did you prune them? What 
surprised me here was that the number is significantly higher than I 
expected; but it seems that there are usually one or two very large 
interfaces (CPlayer in Tweak for example carrying 400 methods) and I 
think it's not too uncommon to have a "handful" of classes that come in 
in the 50-100 methods range.

In any case, this is extremely interesting data.
