FVWM: Focus window based on class or resource

[Thomas Glanzmann]

Hello,
I use evince as pdf viewer. They recently changed the Name and Icon Name
to the name of the pdf. Now I'm unable to use my previous keybinding to
bring evince to focus. Is there way to use Next and specify 'Class' which is
Evince or 'Ressource' which is evince?

Key     A       A       SC      SmartStart "evince"

AddToFunc SmartStart
        + I Next ($0) Iconify off
        + I Next ($0) Raise
        + I Next (AcceptsFocus, $0) focus
        + I None ($0) Exec exec $1

Cheers,
        Thomas
