[Frama-c-discuss] Using Frama-C as Caduceus

Hopefully, the jessie plugin of Frama-C provides some improvement over 
Caduceus. Clearly, there is no chance that you get exactly the same
PVS file.

Now, I understand that you think the PVS file obtained via 
Frama-C/Jessie/Why is significantly more complex than the one you got 
from Caduceus/Why. Indeed, we are willing to improve Frama-C/Jessie 
output if you request for precise feature wishes.
