XML letter

[Mansour <mansour77+docbook@ownmail.net>]

Hi every body:
I am new to docbook, coming from long trip with tex and latex. Decided 
to move ahead and learn about docbook with XML, in order to take 
advantage of the extensibility.
The question now, how do I write letters in docbook ?? Where can I find 
tutorials ?? I'm looking to generate a pdf document with header and 
footer, How ??  Can anyone kindly point me. By the way, I'm using 
docbook-utils on Fedora 4. Had hard time to generate a document with 
docbook. So I will stick to this for now.
