Hi Dave,

I just added an account "mt2" ... because "mt" was already taken. :)

Best,
Marcel

I put my initial change set on SqueakSource at http://www.squeaksource.com/EtoysProject.

This is intended as a temporary SqueakSource project for working out how
to structure EtoysProject and get it to open a new project with the familiar
playfield.

Hannes, Tobias, Bert and I have write access, and I would like to add Marcel
if he has a squeaksource.com account (I could not find it). Please commit
anything that you thimk makes sense.

As you may have guessed by now, I do not actually know enough about Etoys
to make it work. I just put that change set out to see if I could Tom Sawyer
a few of the more knowledgable folks to doing the hard parts. I think it
might be working :-)

I think that the Etoys package in trunk is probably too large for us to be
doing a lot of experimental changes right now, so my hope is that by putting
the Project related part into its own package temporarily, and putting that
up on squeaksource.com, that we can get this part working well enough
to merge back into Etoys in trunk when it is ready.

>From my point of view, "working well enough" means:

- Open a new EtoysProject in Trunk, and the result is an Etoys playfield
that is reasonably similar to a stand-alone Etoys image. The new project
should open with the little car driving around, and with tabs and menus
as expected for Etoys.

- Returning from that Etoys project brings you back to a project that
still works. Whatever preferences were established or overridden to make
Etoys work should be restored so that the other projects are not affected.

Dave
