When it comes to using CVS with Squeak Martin Kobetic is your man. :-) He is one of the CVSTProj
members and he has done most of the fully functional CVS integration in VW/Squeak/Dolphin (but not
the ports). Personally I have focused on the client/server protocol and that is not yet ready -
but it might show up soon in Stable Squeak, who knows. Stable Squeak has as a semiofficial goal to
be able to use CVS as a storage backend for the repository mechanisms.

My small revision to this proposal would be to start with focusing on the VMs and plugins and
waiting a second with the "image"/class libraries. That will be a good chunk of work anyway since
there are a whole range of ports. This way we might also get some good timing with the very
imminent first "release" of Stable Squeak. More below.

Modularity is one - or should I say - THE main focus of the work being done in Stable Squeak. As
my teaser for the next article said - StSq has an ENVY-killer in the making... Tremendously

These actions that you describe are exactly what StSq has been doing. They have broken down a
minimal image with refactorings and written a whole bunch of unit tests for it.

Why not just merge this mailinglist with the (nonexistant) "Stable Squeak mailinglist"? StSq is in
dire need of one and I have been very close to setting one up - I have installed mailman but I
haven't gotten around configuring it. You have done that so could you set one up? StSq would be
grateful - right now we just have an alias "firstname.lastname@example.org" which points to a bunch of people -
a list is better and the connection with SqF should be good. StSq and SqF needs to "connect" I

There is one that was setup for the VM I think. I believe Stefan Rudlof did that a while ago and
there was some heated discussion about it involving Andreas Raab and Ian Piumarta I believe -
can't remember the issues though - but it sort of didn't catch on since Andreas and Ian did not
really "support" it. (My memory may not server me right...)

Ok, this is where CVSTProj comes in. That project IS hosted on SF right now - go and take a look.
The code is fully functioning and Martin Kobetic is the guys who knows the most of it. But it uses
an external executable CVS right now. A coming version would use my protocol implementation but we
haven't gotten there yet.

These things has been discussed at lenght on the Squeak ML. But I do not remember the results! :-)
As a sidenote - we are setting up a public new Swiki for StSq later today in preparation for the
If anyone is thinking of taking action on these things described above - do get in contact with
StSq first (using email@example.com for now) and check out what already is done!
PS. I am sort of taking the role of StSq-nag-person, the guy nagging everybody... :-) DS
