Evaluation net editor

Question

I am looking for a editor for Evaluation nets (E-net, extension of Petri nets).

Something like:

• PIPE2, or
• WoPeD, or
• Yasper (but it not open source and works on Windows only).

I only found that question and not found anything about the result of his works.

I am using evaluation net instead of petri net for modelling agent-based negotiation protocols because in this issue the diagrams are easier to read.
