NAME
       Q - support for Forall, Exists, etc in GNU C and C++

SYNOPSIS
       #include <Q.h>

       bool A(init,cond,next,exprn) /* Forall */

       bool E(init,cond,next,exprn) /* Exists */

       bool E1(init,cond,next,exprn) /* Exists a single */

       bool C(init,cond,next,exprn) /* Count */

DESCRIPTION
       This is a simple minded implementation of predicate calculus in C.  The
       first three arguments are the same as those of the for loop  in	C  and
       C++.   For  example  to verify that all values in an array are positive
       you could use:

       A(int i = 0, i < 100, i++, a[i] >= 0)

       Note that the macros can be nested or used in any context that requires
       boolean values.

       See nana.info for more details.

PORTABILITY
       These macros require GNU C or GNU C++.

       The nana.info page is the primary documentation for this package.
