OK, I thought for a bit that enthusiasm had been lost. There were a
couple of quick and positive responses, though, and I'm glad you got a
chance to take a look too.

I am actually invoking things directly using Pulse. Pulse checks out
the source from svn and I use Pulse commands to run the build, in a
similar way to how other testing scripts appear to work:
I had some trouble figuring out the latest and best way to run tests,
but this seems to work.
The default Pulse behaviour is to do a full clean checkout and build.
However, there is an option to switch to incremental builds, where the
same working copy is used for every build after an svn update to the
desired revision. The reason I steered clear is that I noticed a
mention somewhere in the regression testing documentation that
incremental builds were not 100% reliable.
As suggested elsewhere, breaking things down library by library would
also help. I have noticed a bit of discussion going around about this
lately, and have to say that I think it would be very helpful for
integration with Pulse. Apart from faster builds, it would also make it
easier to see the status of each library if it were a top-level Pulse
project, and developers could then subscribed to email/jabber/RSS
notifications for just the libraries they are interested in.

Glad you like it :). Using an alias will work fine, that is what
aliases were added for.

OK, sounds good.

OK. I need to understand these a bit better before I continue. I am
not sure at what stage in the process these normally take effect. I
guess a lot of the failures I am getting now are actually known and
included in this markup? I need to find some time to dig into this.

OK, thanks. Getting to a state where a normal build is green will make
things a whole lot more useful.
