how to configure gitorious to trigger jenkins build hook

I'm new to using gitorious and wish to trigger a jenkins (also a newbie) build on push . What is the simplest example to set this up?

It can be managed:

• by a script called custom-post-receive, in the data/hooks folder of your gitorious installation on the server.
• or by WebHooks (also on the Gitorious server side)

Since issue 99, Jenkins will be listening for those Gitorious hooks.
The Gitorious plugin for Jenkins also manage that hook.
