How do you write a treatment?

[AmIWriteOrAmIWrite]

I am on my third script, and I have decided to write a treatment for it. I know that a treatment is a summary of the story, but I don't know all the specifics of it. Would you guys be kind enough to fill in the gaps in my knowledge?

I'm wondering:

1) Is a treatment written in the present tense?
2) Should a treatment include the motivations and inner thoughts of the characters, or just action?
3) Do you include character sketches or bios in a treatment?
4) Can anyone point me to an example of a good treatment somewhere on the web?

Thank you very much for your help.

If the treatment is for you it doesn't matter what it looks like or how it is written or what it includes. All that matters is that it helps you clarify the beats and their placements in your story.

If the treatment is something you need for a producer or agent, then I'd suggest you check out the "proper treatment" article on www.wordplayer.com (http://www.wordplayer.com)

I'd also search these boards because this has come up many times. Here's a link to a recent thread: Treatment Thread (http://pub130.ezboard.com/fdonedealfrm23.showMessage?topicID=1244.topic)

Thank you, Deux, this was very helpful.

It actually looks like there are a number of different ways of doing treatments, which is encouraging. The "Sinbad" format, where the writer includes character sketches, is the one I will use.
