Okay? Is that a Zope list or a python one? In Gmane?

Hanno did some digging and found it was under-documented. It *does* work 
though (try it if you'd like).

Basically, that I want the eggs in my buildout to track svn. The way we 
do that now is that we use svn:externals to get them into src/ and then 
use them as 'develop' eggs. However, if I have a different project that 
wants to track Plone svn, I'd rather not have to check out the source 
code like that.

I don't know why the # is needed, this is just the way I've seen it 
spelled before.

I think the default semantic would be that the version would be ==dev 
i.e. current svn. I don't fully understand how this works though - I 
know I can do "easy_install PasteScript==dev" to get the current 
development version of PasteScript, but I don't know how easy_install 
actually finds that (I presume the cheeseshop tells it about 
PasteScript's svn location?)
