> How to prepare it:
> - use QuiteSmall image (http://www.swerlingphoto.com/squeak/ 
> QuiteSmall-3.7.zip)
> - load Mirrors.1.cs
> - load Bootstrap.st
> - evaluate "Bootstrap start"
> - in console type "Bootstrap revert"
> - wait a while
> - condense changes, clear transcript, save image

> How it works:
> - for all classes in system "mirrors" are created. Mirrors are  
> classes with prefix "Xxx" that contain only class definition and  
> methods. They contain no valid references to class variables.
> - mirrors are modified so they contain whole class hierarchy for  
> new system. There are original classes used in code of methods.
> - initial cleanup is executed and system processes are recreated
> - for all original classes, methods of mirrors are assigned.  
> Methods that aren’t in mirrors are removed. Then the new definition  
> of class is used.
> - unnecessary original classes are removed
> - mirrors are removed
> - whole sources are recompiled
> - additional cleanup is executed
>
> The console is very simple. Now it cannot simulate FillInTheBlank,  
> confirmations, user interrupt etc.

> Feel free to clean, improve and fix this image. I have to say that  
> I’m VERY tired of creation of this image now and I need a pause :-)
