Exporting TextEdit document with Applescript

All I want to do is export a TextEdit document as a pdf, a simple menu command, but can't seem to work out how. I've been looking around but I can't seem to find anything anywhere on this, maybe I'm looking in the wrong places but I assume something like this would be fairly straight forward. I assume someone somewhere has done this before, please help...

Thanks!

(I have been working with applescript for a little while so I have a basic understanding.)

P.s. Sorry if this is posted in the wrong space, I couldn't find an applescript section...
