Ressource : ATB*PR*BRPR_Path.
Valeur : path to the file containing the user rules.
Signification : File containing user rules that are automatically loaded at prover startup.
The .pmm files ((see chapter 6 page §)) allows adding rules for proving a component. The user rules base is a similar mechanism that allows adding user rules globaly into Atelier B. The file referenced by the ATB*PR*BRPR_Path ressource contains a set of theories that are automatically loaded at prover startup.
Additionally, the three theories BRPR_Backward, BRPR_Simplify and BRPR_Forward can be defined. Those theories are directly used by the automatic prover, and can be used to improve the automatic proof results.
The BRPR_Forward theory has to be defined as THEORY BRPR_Forward IS Tac(T) END, and the BRPR_Backward and BRPR_Simplify theories contains proof rules.
