# ABSTRACT: Alias one module as another

=head1 NAME
alias::module - Alias one module as another
=head1 VERSION
This document describes version 0.003 of alias::module (from Perl distribution alias-module), released on 2023-09-30.
=head1 SYNOPSIS
 package Your::Alias::Name;
 use alias::module 'Some::Real::Module::Name';
To avoid require()-ing:
 use alias::module '-norequire', 'Some::Real::Module::Name';
=head1 DESCRIPTION
This module aliases one module name to another.
 package Your::Alias::Name;
 use alias::module 'Some::Real::Module::Name';
is equivalent to:
 package Your::Alias::Name;
 BEGIN {
     $Package::Alias::BRAVE = 1;
     require Some::Real::Module::Name;
 }
 use Package::Alias 'Your::Alias::Name' => 'Some::Real::Module::Name';
except that this module does not use L<Package::Alias> and is simpler. It is
useful if you want to let users access a module's functionality under a
different (usually shorter) name.

=head1 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 L<Dist::Zilla>,
L<Dist::Zilla::PluginBundle::Author::PERLANCAR>,
L<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.

=head1 BUGS
Please report any bugs or feature requests on the bugtracker website L<https://rt.cpan.org/Public/Dist/Display.html?Name=alias-module>
When submitting a bug or request, please include a test-file or a
patch to an existing test-file that illustrates the bug or desired
feature.
