Select a mesh in bind pose, then go to the Bulge_fix_dqs shelf, and click on the 2nd icon to create a node deformer:

In the attribute editor, you can change the "envelope" or turn on the "Live skin weights update", the latter allows you to edit skin weights when a Bfix_bulgeFixDeformer node already exists (slower). Changes to mesh shape, joint numbers, or hierarchy will require you to erase and recreate the Bfix_bulgeFixDeformer node.

The 3rd icon allows you to paint areas where you apply the bulge fix.
