Name        : why
Product     : Fedora 22
Version     : 2.34
Release     : 20.fc22
URL         : http://why.lri.fr/
Summary     : Software verification platform
Description :
Why is a software verification platform that applies formal proving
tools to annotated programs.  It is currently capable of analysis of C
(through "Frama-C"), Java (through the included tool "Krakatoa"), and
potentially ML programs with some modification into Why's own ML-like
language.  Furthermore, Why is capable of analysis of any program that
is mapped onto its own internal language.  It uses a weakest
precondition involving calculus to generate potential theorems necessary
for the proof of a program's correctness.  It translates these theorems
into formats that can be used by external proof assistants (without any
extra work Coq, PVS, HOL Light, and Mizar are supported - having one is
recommended and both Coq and PVS are packaged for Fedora) and automated
theorem provers (without any extra work Simplify, Alt-Ergo, Yices, Z3,
CVC3, and Zenon are supported and Alt-Ergo, CVC3, and Zenon are packaged
for Fedora) so that these results can be externally proven, resulting in
a proof of program correctness.

Note: Each user account must be set up by running "why-config" at the
command line (to set up a configuration file).
