I want to automate the process of plone3_buildout.

Explanation: The default(the one I use) way of building a plone site is using paster, like so:

paster create -t plone3_buildout

This asks me a few questions and then create a default buildout for the site.

What I want: I want to automate this process using buildout. My buildout will execute this paster command, feed in my preconfigured values to the paster.

I haven't found a recipe which can do this. If someone has an idea of how to do this, please share the info.

If there is a recipe which can feed values to interactive commands(with known output, like with plone3_buildout command), that would be useful too.
