  Sorry not for getting back to you sooner when you complained, err,
expressed the idea.  It is a kind of "slow-death" and delaying an
action is always easy.

  Now, if we do the following:

  - Condensing sources
  - making EtoysV1.sources (or EtoysV3.sources, actually)
  - Bumping the base version number to 3 and make etoys-3.0-dev.image
  - Creating a new update stream for it.

We are good to go.

Yes, I confirmed that condenseSources manages to keep the class
comment stamps.
