Listing buildout configuration variables

Question

I'd like to find out, exactly what variables are available when using zc.buildout. I can always look at the source, but ideally I'd find a list somewhere, or be able to query buildout to find out what it thinks are the variables available at any one time. Is this possible?

Answer 1

I found from the buildout docs that

bin/buildout annotate

was what I was looking for.

Answer 2

It is not the prettiest list, but you can look at .installed.cfg in your buildout's directory.

For every part, it shows which options it knows about. (For some reason several parts are often shown multiple times).
