[Frama-c-discuss] WG: binary_search example



Hi,

The binary search examples in the jessie tutorial should be a reference 
for that:

  http://frama-c.cea.fr/jessie_tutorial_index.html

the lemma is proven only by Yices.

Note that the tutorial was run under Lithium, under Beryllium-beta you 
might face small differences: in that case do not hesitate to tell us 
which differences you have.
