Gah. Yeah. Sorry. You might get away with creating and installing

I find Ian Bicking's virtual_python.py script very useful for trying
things like this out. I usually install both a custom version of
Python and one or more virtual pythons in my automated scripts (using
the --no-site-packages flag to virtual_python.py). This means I can
let distutils/setuptools packages install to site-packages "normally"
without polluting the main Python installation's site-packages and so
I don't need to go through gyrations to munge the PYTHONPATH for them
to be found somewhere else. I think buildout tends to prefer

Currently we use svn bundles of Zope and Plone and our own packages and products in one big svn:externals definition. We also use some more recent versions of certain products and packages than those included in the upstream svn:externals. For example: Zope svn://svn.zope.org/repos/main/Zope/branches/2.10 Zope/lib/python/zope/app/interface svn://svn.zope.org/repos/main/ zope.app.interface/trunk/src/zope/app/interface Though I haven't seen any documentation to this effect, svn seems to treat the second svn:externals as a "svn switch" on "svn up". So one question I have is how would I "override" the versions of some package like this using buildout? Putting these packages in your Zope instance home's "lib/python" directory should get them found before the others. For Products, you can use an additional "products-path" directive in zope.conf and put files in there. I don't know how to tell buildout to do either, though. Another question I have is that there aren't releases for all the dependencies our application has. I'm wondering what the best way is to define a canonical release for deployment to our cluster. Ideally, we'd have a buildout (or whatever) on a staging server where we're testing the candidate for deployment and then when all tests pass that *exact* source should be deployed to the cluster. I always use a vendor import for this (to a separate CVS server, I don't use SVN). How might one do this without upstream releases? Is there a way to get buildout and setuptools to play together so that I can build a source distribution from the test passing buildout on staging? Is there a way I can have a buildout on each cluster node such that a simple ./bin/buildout will get the latest deployment release for that node? Personally I use a script that knows about all of the revisions of all of the products and packages I want to deploy, and which creates a "sandbox", downloading and installing all of them (as well as creating instances, etc).

Thanks for the links, I'll try installing docfindertab soon as I can.
I'm trying to read a property of a file and the description of it on the
plope site is too terse for me to understand. Here is my code:
doc=getattr(context, filename)
getname=doc.manage_getProperty('user_name')
filename is a parameter passed to the python script, it the name of the
file I'm wanting a property of. I've tried several ways of specifying the
property and none of them work. The property is called user_name, its a
string. Above I'm using quotes to make it a string passing it by value,
I've also done it by assigning a variable the property name, etc.
I also tried it with the optional 2nd argument with different variables like:
getname=doc.manage_getProperty('user_name',d=None)
I've tried not assigning it to a variable, all kinds of minor syntax
changes, but nothing I do works, it gives the same error:
Error Type: AttributeError
Error Value: manage_getProperty
