Question about Headers & Footers and Emphasizing Words

["Bryan Richardson" <btricha@gmail.com>]

Hello all,

I'm totally new to DocBook and am creating a "test" document to try and figure out how to implement the features I use most.  Can anyone tell me how to add/modify header and footer text in a document?  Also, I notice that <emphasis> will put words in italics, but how do I bold a word?

Thanks! -- BTR
