[news.eclipse.modeling.mdt] [UML2] Tutorials on use-case diagrams?

["John E. Conlon" <jconlon@xxxxxxxxxx>]

Hi,

I wish to use the uml2 tools to document use-cases for a client.  Where 
can I find documentation, tutorials, or samples on how to use the 
use-case diagram tools?

Currently using docbook as a framework for documentation and would like 
to add to the eclipse-help and pdf artifacts created by my documentation 
build use-case diagrams created from uml2 tools.  Can anyone recommend 
'best-practices' for integrating the use-case diagrams created with the 
uml2 tools with external textual documentation like docbook?

thanks for any help or suggestions,

cheers,
John
