NAME
    Module::CheckLatestVersion - Warn/die when a module is not the latest
    version

VERSION
    This document describes version 0.003 of Module::CheckLatestVersion
    (from Perl distribution Module-CheckLatestVersion), released on
    2026-04-08.

SYNOPSIS
    In Your/Module.pm:

     package Your::Module;

     use Module::CheckVersion; # automatically exports 'check_latest_version'

     our $VERSION = 1.23;
     our $AUTHORITY = 'cpan:PERLANCAR';

     check_latest_version();
     # check_latest_version({die=>1});

    If module is not the latest version (checked against authority) then a
    warn message is displayed. If the "die" option is set, program will die.

    Or, alternatively, in your-script.pl:

     #!perl

     use strict;
     use warnings;
     use Module::CheckLatestVersion;
     use Your::Module;

     check_latest_version("Your::Module");
     #check_latest_version({die=>1}, "Your::Module");
     ...

DESCRIPTION
    This module can be used to check other module's version against latest
    version in authority. Authority can be CPAN or DarkPAN or other schemes
    that are supported by Module::CheckVersion.

    Checking against authority is cached, by default 3600 seconds (default
    from Cache::File::Simple).

    This can be used to ensure that scripts use the latest version of a
    module.

FUNCTIONS
  check_latest_version
    Usage:

     check_latest_version([ \%opts, ] [ $mod ])

    Check module $mod against authority (default is CPAN), using
    Module::CheckVersion. $mod defaults to the caller's package. If module
    is not the latest version, a warning is emitted.

    When one of these environment variables are set, will skip checking
    (no-op): "HARNESS_ACTIVE", "RELEASE_TESTING", "AUTOMATED_TESTING",
    "PERL_MODULE_CHECKLATESTVERSION_SKIP".

    Options:

    *   die

        Bool. If set to true, will die instead of warn.

ENVIRONMENT
  PERL_MODULE_CHECKLATESTVERSION_OPT_DIE
    Bool. Set default value for the "die" option.

  PERL_MODULE_CHECKLATESTVERSION_SKIP
    Bool. Can be set to true to skip checking.

CONTRIBUTING
    To contribute, you can send patches by email/via RT, or send pull
    requests on GitHub.

    Most of the time, you don't need to build the distribution yourself. You
    can simply modify the code, then test via:

     % prove -l

    If you want to build the distribution (e.g. to try to install it locally
    on your system), you can install Dist::Zilla,
    Dist::Zilla::PluginBundle::Author::PERLANCAR,
    Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two
    other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps
    required beyond that are considered a bug and can be reported to me.
