Add signature programatically

Hi,
How do I add signature programatically. i have a text file with a qote, everytime, i open outlook, the quote should be read and it will be my signature, till i close outlook. i may change the quote in the text file periodically.
Now my basic question is, which api should be used to set a signature.

No need for an API. Outlook's settings provide a spot to specify your signature in. No point reinventing the wheel just so you can edit a text file instead of an option.

Thanks, But i kept my question simple, for easy understanding. I actually wanted to write a script, that takes the first quote from the file containing a list of quotes and make it as signature and either remove the quote from the file or put it at the end, so that i have a new quote each day as my signature.
Now, the setting, just takes the entre file as signature. Can I specify only the first line or something there????

I tried pointing a file as signature and kept changing the text of the file. IT DIDN"T WORK. The text that was in the beginning when I assigned, still remains as signature even after changign the contents.
