Note that browsing through the source "an egg at a time" is sometime  
nice, since you are working with fewer files (and you can make some  
nice shell aliases for opening an egg in your editor quickly), but if  
you want to dump all the eggs into the pan and see them all at once  
you can make an omelette with collective.recipe.omelette. This is as  
easy as:

[buildout]
parts = ... omelette

[omelette]
recipe = collective.recipe.omelette
eggs = ${app:eggs}

Re-run ./bin/buildout and you'll see a collection of symlinks in ./ 
parts/omelette/ that let you browse the source as a cohesive whole :)
