[Zope] zc.buildout and zope2.12

Hey! I am new to the /zc.buildout /tools and python packaging. I would like to have buildout.cfg file which should look like this: [buildout] parts = zope2.12 zope_instance product1 product2 ... [zope2.12] recipe = zc.recipe.egg ... [instance] recipe = plone.recipe.zope2instance ... [product1] recipe = ? eggs = ... [product2] recipe = ? eggs = ... .... So I would like to have zc.buildout to grab zope from the net, make zope instance and put somehow [my problem] those product parts into zope instance. Do you have any suggestions or do you now some recipes or perhaps could you give any tips about installing products into instance. There is not much time so I`m asking you for a little help :) Regards, Jonas
