Experiences Squeakers, let me understand this problem some more. I understand 
how a changeset can contain code that "belongs" to several Monticello 
Packages. What I do not know is how much code is currently maintained in 
Monticello vs Changesets. Let me analyse this further: I looked at 3 
SqueakMap projects. One is maintained my PR, another by a CS, last one by 
MCZ - here


So as far as code on SqueakMap, it is a mixture. Another question is: Of the 
current 3.9 image, are there any parts maintained by Monticello? For example, 
if I want to change something in Collections (and I mean this purely as 
example, my question is about all the 3.9 image code): is there a MCZ for 
Collections, or do I have to make my change, and, if I want to share it, 
create a CS?

I am trying to understand how to relieve the 3.9 harvesting problem Ralph 
described above from Markus. (more notes below)

I do not know, but I am trying to think how one would write such tool. First, 
what is the code "managed" by one Monticello package, is fairly simple to 
define: Let's say there is a Monticello Package named ABC. This Abc Package 
manages (simplifying, just to clarify the point):
	- all classes in system categories with names starting with "Abc".
	- all method with method category names starting with "*abc".
	- all methods in classes that are in system category starting with "Abc"
So it seems that if the tool would look into the changeset, look what are the 
categories, class and method names contained there, and applies those rules, 
it should be able to generate a list of Monticello packages which the CS 
_potentially_ affects. The reason I am saying _Potentially_, is because such 
Monticello package may not even exist. So it seems on top of the logic I 
think should be doable, there needs to be a "global" Squeak list of 
Monticello packages in existence, and the tool would intersect the result of 
it's step1 automatic analysis with this "global list".

Does this make any sense at all....

First I revert to wait state as maybe such tool exists already and someone 
will reply :)
