NAME

6       Alien::Util - Alien Utilities used at build and runtime
7

VERSION

9       version 2.80
10

SYNOPSIS

12        use Alien::Util qw( version_cmp );
13

DESCRIPTION

15       This module contains some functions used by both the Alien::Build
16       build-time and <Alien::Base> run-time for Alien.
17
18   version_cmp
19         $cmp = version_cmp($x, $y)
20
21       Comparison method used by "atleast_version" in Alien::Base,
22       "exact_version" in Alien::Base and "max_version" in Alien::Base. May be
23       useful to implement custom comparisons, or for subclasses to overload
24       to get different version comparison semantics than the default rules,
25       for packages that have some other rules than the pkg-config behaviour.
26
27       Should return a number less than, equal to, or greater than zero;
28       similar in behaviour to the "<=>" and "cmp" operators.
