1) Tied scalar, where reading from the scalar retrieves the current working
directory and writing to it changes the working directory. The user can set the
magic variable locally and have Perl restore the old value. Modules that use
this technique include: L<File::chdir>.

2) An object, where its constructor records the current working directory and
its DESTROY restores the previously recorded working directory. The user can
create a lexically scoped object that can change directory but restores the
previous working directory when the object goes out of scope. Modules that use
this technique include: L<File::pushd> and L<Dir::TempChdir>.

=head1 FAQ

=head2 What is an Acme::CPANModules::* module?

An Acme::CPANModules::* module, like this module, contains just a list of module
names that share a common characteristics. It is a way to categorize modules and
document CPAN. See L<Acme::CPANModules> for more details.

=head2 What are ways to use this Acme::CPANModules module?

Aside from reading this Acme::CPANModules module's POD documentation, you can
install all the listed modules (entries) using L<cpanm-cpanmodules> script (from
L<App::cpanm::cpanmodules> distribution):

 % cpanm-cpanmodules -n TemporaryChdir

Alternatively you can use the L<cpanmodules> CLI (from L<App::cpanmodules>
distribution):

    % cpanmodules ls-entries TemporaryChdir | cpanm -n

or L<Acme::CM::Get>:

    % perl -MAcme::CM::Get=TemporaryChdir -E'say $_->{module} for @{ $LIST->{entries} }' | cpanm -n

or directly:

    % perl -MAcme::CPANModules::TemporaryChdir -E'say $_->{module} for @{ $Acme::CPANModules::TemporaryChdir::LIST->{entries} }' | cpanm -n

This Acme::CPANModules module also helps L<lcpan> produce a more meaningful
result for C<lcpan related-mods> command when it comes to finding related
modules for the modules listed in this Acme::CPANModules module.
See L<App::lcpan::Cmd::related_mods> for more details on how "related modules"
are found.

=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.
