How do I open a folder in Textmate with Applescript?

Question

So I've opened Textmate using Applescript, how do I tell it to open a specific folder?

EDIT: Tried Josh K's suggestion, but a strange error occurs. I ran this line:

do script "mate rails_projects/newproject"

And here is the result:

bens-macbook-pro:~ ben$ mate rails_projects/newproject
mate: failed to establish connection with TextMate.

But then, in the same console window, I'll type the same line that just failed,

bens-macbook-pro:~ ben$ mate rails_projects/newproject

and it works. Why would this be happening?

Answer 1

I would point the AppleScript to run the mate [folder] command, which will open TextMate with the specified folder.
