Yeah, but I am semi sick right now so little energy when evening comes.
And busy at work.
I will try to wrap it up tomorrow though.

Which will nuke *all*, initialize, load sample data.

Which fires up all services (Seaside, Scheduler yaddayadda).

Might be a bit faster, not sure. We haven't done any serious performance
tweaking yet. Readstrategy might be worth looking at. And also - right
now all Seaside components are initialized on login - which explains why
it takes a while to get in. We could do it when people click around in
the left area on demand instead.

Well, almost. :) We have also upgraded other packages, I will try to
list all used versions when doing the 0.2 release, and there is also a
Changeset we maintain with "various fixes" that should be installed.

I am right now trying to prepare a semi auto loadscript that builds the
dev image from a vanilla 3.8 image - which makes it easier for anyone
that wants to "build from scratch".

There have been quite a few model changes and also a Magma change that
makes it hard to migrate an old db. BUT... with 0.2 we have a working
txn engine - we have actually streamed out all txns, wiped the db and
then rebuilt it by applying all those txns from the file.

This is actually a great way to migrate old dbs - the Txn classes tend
to not change that much. Or at least they will not, when they have
matured a bit.

Thanks for being on the bleeding edge! :) Feel free to ask more.
