[Zope] zc.buildout and zope2.12

[jonas]

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
