So, from your example, you now have a kss.core-0.1dev egg. It isn't
a real release. It reflects the state of your subversion repository
at the time you happened to run the buildout.
My guess is that if you run the buildout again, the egg won't be
recreated. You won't be tracking subversion changes as you wished.
Further, if you use a shared eggs directory, any other buildouts will
likely use that same egg, which has a more or less random snapshot of
the software. I suggest that this is a bad thing.
IMO, this is what you really want:
- You want something to check out your project and make it a develop
- When you run buildout later, you want something to do an svn up in
the checkout and to rerun setup (in case there are extensions).
I think this "something" should probably be a recipe (or a feature of
some existing recipe).
I wonder what easy_install does in a case like this. For example, I
wonder if easy_install would download and rebuild the egg every time
you ran it. Of course, with easy_install, you probably would only
run it once, but, again, then you wouldn't be tracking subversion.
