Not using bootstrap.py as default?

I've just found time to come back & read this. I want to say thanks to Jens - for the virtualenv idea & everyone for the very helpful open discussion. I think the best thing that can be put in the docs is a clear admission that this area gets difficult at times... that should keep new adopters with us, rather than giving up!

Btw yesterday I found the following command which seems like it would help with version conflicts when I get them (is this obvious, or not?) In this example for plone.resource, it shows me what other products require it & what pins they apply:

$ grep plone.resource  eggs/*.egg/EGG-INFO/requires.txt 
eggs/plone.app.theming-1.1.6-py2.7.egg/EGG-INFO/requires.txt:plone.resource>=1.0b5
eggs/plone.app.theming-1.1.6-py2.7.egg/EGG-INFO/requires.txt:plone.resourceeditor
eggs/plone.app.themingplugins-1.0b1-py2.7.egg/EGG-INFO/requires.txt:plone.resource
eggs/plone.resourceeditor-1.0-py2.7.egg/EGG-INFO/requires.txt:plone.resource
