This addon is discontinued.
Spequip is an automated equipping addon that works with the default Equipment Manager.
The only requirement for it to work is to name the sets accordingly to your current talent spec.
If you are "specced" 6/0/35, with 35 talent points in Restoration, you can name the equipment set one of the following:
"6/0/35" or "Restoration"
Note that the name is case-sensitive.
