=head1 DESCRIPTION

This tool reports the locations of installed perl modules.

By default it lists the location of each specified module that would be loaded
by require.

=head1 OPTION DETAILS

=head2 quiet

Under quiet mode, module names are suppressed and missing modules are not
reported.

Normal output:

    $ pm_which Module::One Module::Two Missing::Module
    Module::One     - /path/to/Module/One.pm
    Module::Two     - /path/to/Module/Two.pm
    Missing::Module - not found

Under --quiet:

    $ pm_which -q Module::One Module::Two Missing::Module
    /path/to/Module/One.pm
    /path/to/Module/Two.pm

=head2 paths

In "paths" mode, each module is simply converted into a relative file path. This
is possible even when the module is not installed.

    $ pm_which -p Missing::Module
    Missing/Module.pm

=head2 all

When the "all" switch is specified, all installed modules will be reported, not
just the first one. This is useful for determining when there is a module
installed in multiple locations.

    $ pm_which -a MyModule
    /path/to/MyModule.pm
    /home/me/perl/MyModule.pm

=head2 namespace

Arguments are taken as namespaces to search under.

    $ pm_which -n MyModule
    MyModule            - /path/to/MyModule.pm
    MyModule::Foo       - /path/to/MyModule/Foo.pm
    MyModule::Foo::Bar  - /path/to/MyModule/Foo/Bar.pm

=head2 -m

Disables printing of module paths. This is only really useful in conjunction with --namespace.

    $ pm_which -nm MyModule
    MyModule
    MyModule::Foo
    MyModule::Foo::Bar

=head2 -V

Prints the version of each module, according to L<ExtUtils::MakeMaker>.

    $ pm_which -V MyModule
    MyModule - /path/to/MyModule.pm [ 1.00 ]

    $ pm_which -Vnm MyModule
    MyModule [ 1.00 ]
    MyModule::Foo [ 0.01 ]
    MyModule::Foo::Bar [ undef ]

=head2 dump

Dumps the paths that would be searched and exits. This is @INC modified by any
-I switches.

    $ pm_which --dump
    /usr/lib/perl5/site_perl/5.8.6
    /usr/lib/perl5/vendor_perl/5.8.6
    ...

    $ pm_which -I lib --dump -I blib/lib
    lib
    blib/lib
    /usr/lib/perl5/site_perl/5.8.6
    ...

=head2 version

Prints the version number of the script, plus the version and path of
Module::Util that was loaded.

=head1 EXIT CODES

=over

=item * 0 - Everything was OK

=item * 1 - Initialisation failed (bad switches?)

=item * 2 - Some modules were not installed

=back

=head1 SEE ALSO

This utility comes with L<Module::Util>.
