A new version of SystemEditor was added to project SystemEditor:
http://www.squeaksource.com/SystemEditor/SystemEditor-mtf.154.mcz

==================== Summary ====================

Name: SystemEditor-mtf.154
Author: mtf
Time: 6 November 2008, 11:34:51 pm
UUID: ff37b66e-bb9e-46e1-86ab-cde14ca663c1
Ancestors: SystemEditor-mtf.153

moved around classes and extensions to be in two categories: core and squeak. This is the last commit in this line: I am being split up into three packages: core, squeak, and tests.

Also removed one useless class and one useless extension

  I remember what subclasses were added to or removed from my parent. Since the subclass list can be nil at times, I cannot migrate it, so I work in edPostLoad!

  An abstract superclass for editors of Categorizers. Implements the public interface of a Categorizer. I maintain the list of added, removed, or reordered categories, but it is up to subclasses to remember which elements were added, removed, or recategorized.
  
  subject (Categorizer) - The Categorizer I am editing
  categories (OrderedCollection) - The ordered list of categories
  renamedCategories (Dictionary) - A dictionary mapping old category names to new names!

  My instances represent ClassEditors on the concept of "ProtoObject's superclass", the primitive object from which every class, without exception, inherits. I exist so that queries that involve the superclass do not have to be special-cased in case the superclass really is nil.!

  I am an expert on the way the Squeak VM encodes class formats. My instance variable, 'bits', is identical in format to the 'format' instance variable of Behavior. I have methods for interpreting those bits. The class format integer is 18 bits in length. The instSize field is split into two parts for backwards compatibility.
  
  <2 bits=instSize//64> <5 bits=cClass> <4 bits=instSpec> <6 bits=instSize\\64> <1 bit=0>
  
  - instSize: the number of named instance variables
  - cClass: the index into the compact class table
  - instSpec: values indicating how instances are organized
  	0 - no state
  	1 - named instance variables only
  	2 - variable number of object pointers
  	3 - named instance variables, variable number of object pointers
  	4 - variable number of weak object pointers
  	6 - variable number of words
  	8 - variable number of bytes
  	12 - compiled method format: variable number of object pointers, variable number of bytes!

  I am an abstract superclass for both ClassEditor and MetaclassEditor.
  
  I implement  the Behavior protocol: my instances can create instances. This means that my first three variables must remain 'superclass methodDict format', as the VM accesses them positionally, and my superclasses must not define any instance vairables. Only MetaclassEditor makes use of these ivars, but they are defined here to avoid duplicating a lot of ivars and accessing methods between ClassEditor and MetaclassEditor!

  - add each class to its superclass's subclasses list
  - add each class to the SystemDictionary Smalltalk!

  I have no idea what this class is for. It is extensivily tested in SystemEditor-Tests, but it is actually only used two places in the code:
  OrganizationEditor>>writeComment
  MethodEditor>>logCompilationFrom:for:
  
  I have not examined to see what it does -- Matthew Fulmer!
