NAME
       Alien::Util - Alien Utilities used at build and runtime

VERSION
       version 2.80

SYNOPSIS
        use Alien::Util qw( version_cmp );

DESCRIPTION
       This module contains some functions used by both the Alien::Build
       build-time and <Alien::Base> run-time for Alien.

   version_cmp
         $cmp = version_cmp($x, $y)

       Comparison method used by "atleast_version" in Alien::Base,
       "exact_version" in Alien::Base and "max_version" in Alien::Base. May be
       useful to implement custom comparisons, or for subclasses to overload
       to get different version comparison semantics than the default rules,
       for packages that have some other rules than the pkg-config behaviour.

       Should return a number less than, equal to, or greater than zero;
       similar in behaviour to the "<=>" and "cmp" operators.
