Name        : why3
Product     : Fedora 21
Version     : 0.85
Release     : 3.fc21
URL         : http://why3.lri.fr/
Summary     : Software verification platform
Description :
Why3 is the next generation of the Why software verification platform.
Why3 clearly separates the purely logical specification part from
generation of verification conditions for programs.  It features a rich
library of proof task transformations that can be chained to produce a
suitable input for a large set of theorem provers, including SMT
solvers, TPTP provers, as well as interactive proof assistants.

Update Information:

The alt-ergo, frama-c, ocaml-tplib, and why3 builds are simply rebuilds for ocaml-zarith 1.3.  The upstream notes on this version of ocaml-zarith are:
- Fixed inefficiencies in asm fast path for ARM.
- Revised detection of NaNs and infinities in Z.of_float
- Suppress the redundant fast paths written in C if a corresponding fast path exists in asm.
- Use <stdint.h> to ensure compatibility with OCaml 4.02.
- More prudent implementation of Z.of_int, avoids GC problem with OCaml < 4.02 (PR#6501 in the OCaml bug tracker).
- PR#1429: of_string accepts 'a' in base 10.
- Macro change to avoid compiler warnings on unused variables.

This update can be installed with the "yum" update program.  Use
su -c 'yum update why3' at the command line.
