Use Case Tutorial

Hello.  I'm new to Use Cases and ArgoUML.  I've searched web for both Use
Case tutorial's and Use Case tools.
So far I've not come across any info. on how to actually construct use cases
using Argo.
I've found a lot of basic tutorials but nothing  that gets into all the
options that Argo has e.g.all the attributes for the Properties of a Use
Case
Can anyone on list point me in the right direction?

tx, frank
