That must have been before my time. These days, all versions are stored on
disk. Each chunk has the source pointer for the previous version in it, and
the tools walk back through the changes/source files collecting all the
versions in the chain.

Here's an example:

!MCVersionInfo methodsFor: 'converting' stamp: 'bf 4/18/2010 23:25' prior:
23175569!
asDictionary
^ Dictionary new
at: #name put: name;
at: #id put: id asString;
at: #message put: message;
at: #date put: date;
at: #time put: time;
at: #author put: author;
at: #ancestors put: (self ancestors collect: [:a | a asDictionary]);
yourself! !

That "prior" parameters points to the previous version.
