[Distutils] zc.buildout and zc.recipe.egg

[Miles Waller]

Actually, I'm a bit unclear as to how to test this in a useful way:  do 
you think it is sufficient just to test that the content of the script 
generated contains specific text (that doesn't guarantee the script that 
is generated actually works!)?

Thanks

Miles
