NAME
       CPANPLUS::Module - CPAN module objects for CPANPLUS

SYNOPSIS
           ### get a module object from the CPANPLUS::Backend object
           my $mod = $cb->module_tree('Some::Module');

           ### accessors
           $mod->version;
           $mod->package;

           ### methods
           $mod->fetch;
           $mod->extract;
           $mod->install;

DESCRIPTION
       "CPANPLUS::Module" creates objects from the information in the source files. These can then be used
       to query and perform actions on, like fetching or installing.

       These objects should only be created internally. For "fake" objects, there's the
       "CPANPLUS::Module::Fake" class. To obtain a module object consult the "CPANPLUS::Backend"
       documentation.

CLASS METHODS
   accessors ()
       Returns a list of all accessor methods to the object

ACCESSORS
       An objects of this class has the following accessors:

       name
           Name of the module.

       module
           Name of the module.

       version
           Version of the module. Defaults to '0.0' if none was provided.

       path
           Extended path on the mirror.

       comment
           Any comment about the module -- largely unused.

       package
           The name of the package.

       description
           Description of the module -- only registered modules have this.

       dslip
           The five character dslip string, that represents meta-data of the module -- again, only
           registered modules have this.

       status
           The "CPANPLUS::Module::Status" object associated with this object.  (see below).

       author
           The "CPANPLUS::Module::Author" object associated with this object.

       parent
           The "CPANPLUS::Internals" object that spawned this module object.

STATUS ACCESSORS
       "CPANPLUS" caches a lot of results from method calls and saves data it collected along the road for
       later reuse.

       "CPANPLUS" uses this internally, but it is also available for the end user. You can get a status
       object by calling:

           $modobj->status

       You can then query the object as follows:

       installer_type
           The installer type used for this distribution. Will be one of 'makemaker' or 'build'. This
           determines whether "CPANPLUS::Dist::MM" or "CPANPLUS::Dist::Build" will be used to build this
           distribution.

       dist_cpan
           The dist object used to do the CPAN-side of the installation. Either a "CPANPLUS::Dist::MM" or
           "CPANPLUS::Dist::Build" object.

       dist
           The custom dist object used to do the operating specific side of the installation, if you've
           chosen to use this. For example, if you've chosen to install using the "ports" format, this may
           be a "CPANPLUS::Dist::Ports" object.

           Undefined if you didn't specify a separate format to install through.

       prereqs | requires
           A hashref of prereqs this distribution was found to have. Will look something like this:

               { Carp  => 0.01, strict => 0 }

           Might be undefined if the distribution didn't have any prerequisites.

       configure_requires
           Like prereqs, but these are necessary to be installed before the build process can even begin.

       signature
           Flag indicating, if a signature check was done, whether it was OK or not.

       extract
           The directory this distribution was extracted to.

       fetch
           The location this distribution was fetched to.

       readme
           The text of this distributions README file.

       uninstall
           Flag indicating if an uninstall call was done successfully.

       created
           Flag indicating if the "create" call to your dist object was done successfully.

       installed
           Flag indicating if the "install" call to your dist object was done successfully.

       checksums
           The location of this distributions CHECKSUMS file.

       checksum_ok
           Flag indicating if the checksums check was done successfully.

       checksum_value
           The checksum value this distribution is expected to have

METHODS
   $self = CPANPLUS::Module->new( OPTIONS )
       This method returns a "CPANPLUS::Module" object. Normal users should never call this method directly,
       but instead use the "CPANPLUS::Backend" to obtain module objects.

       This example illustrates a "new()" call with all required arguments:

               CPANPLUS::Module->new(
                   module  => 'Foo',
                   path    => 'authors/id/A/AA/AAA',
                   package => 'Foo-1.0.tgz',
                   author  => $author_object,
                   _id     => INTERNALS_OBJECT_ID,
               );

       Every accessor is also a valid option to pass to "new".

       Returns a module object on success and false on failure.

   $mod->package_name( [$package_string] )
       Returns the name of the package a module is in. For "Acme::Bleach" that might be "Acme-Bleach".

   $mod->package_version( [$package_string] )
       Returns the version of the package a module is in. For a module in the package
       "Acme-Bleach-1.1.tar.gz" this would be 1.1.

   $mod->package_extension( [$package_string] )
       Returns the suffix added by the compression method of a package a certain module is in. For a module
       in "Acme-Bleach-1.1.tar.gz", this would be "tar.gz".

   $mod->package_is_perl_core
       Returns a boolean indicating of the package a particular module is in, is actually a core perl
       distribution.

   $mod->module_is_supplied_with_perl_core( [version => $]] )
       Returns a boolean indicating whether "ANY VERSION" of this module was supplied with the current
       running perl's core package.

   $mod->is_bundle
       Returns a boolean indicating if the module you are looking at, is actually a bundle. Bundles are
       identified as modules whose name starts with "Bundle::".

   $mod->is_autobundle;
       Returns a boolean indicating if the module you are looking at, is actually an autobundle as generated
       by "$cb->autobundle".

   $mod->is_third_party
       Returns a boolean indicating whether the package is a known third-party module (i.e. it's not
       provided by the standard Perl distribution and is not available on the CPAN, but on a third party
       software provider).  See Module::ThirdParty for more details.

   $mod->third_party_information
       Returns a reference to a hash with more information about a third-party module. See the documentation
       about "module_information()" in Module::ThirdParty for more details.

   $clone = $self->clone
       Clones the current module object for tinkering with.  It will have a clean "CPANPLUS::Module::Status"
       object, as well as a fake "CPANPLUS::Module::Author" object.

   $where = $self->fetch
       Fetches the module from a CPAN mirror.  Look at CPANPLUS::Internals::Fetch::_fetch() for details on
       the options you can pass.

   $path = $self->extract
       Extracts the fetched module.  Look at CPANPLUS::Internals::Extract::_extract() for details on the
       options you can pass.

   $type = $self->get_installer_type([prefer_makefile => BOOL])
       Gets the installer type for this module. This may either be "build" or "makemaker". If
       "Module::Build" is unavailable or no installer type is available, it will fall back to "makemaker".
       If both are available, it will pick the one indicated by your config, or by the "prefer_makefile"
       option you can pass to this function.

       Returns the installer type on success, and false on error.

   $dist = $self->dist([target => 'prepare|create', format => DISTRIBUTION_TYPE, args => {key => val}]);
       Create a distribution object, ready to be installed.  Distribution type defaults to your config
       settings

       The optional "args" hashref is passed on to the specific distribution types' "create" method after
       being dereferenced.

       Returns a distribution object on success, false on failure.

       See "CPANPLUS::Dist" for details.

   $bool = $mod->prepare( )
       Convenience method around "install()" that prepares a module without actually building it. This is
       equivalent to invoking "install" with "target" set to "prepare"

       Returns true on success, false on failure.

   $bool = $mod->create( )
       Convenience method around "install()" that creates a module.  This is equivalent to invoking
       "install" with "target" set to "create"

       Returns true on success, false on failure.

   $bool = $mod->test( )
       Convenience wrapper around "install()" that tests a module, without installing it.  It's the
       equivalent to invoking "install()" with "target" set to "create" and "skiptest" set to 0.

       Returns true on success, false on failure.

   $bool = $self->install([ target => 'init|prepare|create|install', format => FORMAT_TYPE, extractdir =>
       DIRECTORY, fetchdir => DIRECTORY, prefer_bin => BOOL, force => BOOL, verbose => BOOL, ..... ]);
       Installs the current module. This includes fetching it and extracting it, if this hasn't been done
       yet, as well as creating a distribution object for it.

       This means you can pass it more arguments than described above, which will be passed on to the
       relevant methods as they are called.

       See "CPANPLUS::Internals::Fetch", "CPANPLUS::Internals::Extract" and "CPANPLUS::Dist" for details.

       Returns true on success, false on failure.

       Returns a list of module objects the Bundle specifies.

       This requires you to have extracted the bundle already, using the "extract()" method.

       Returns false on error.

   $text = $self->readme
       Fetches the readme belonging to this module and stores it under "$obj->status->readme". Returns the
       readme as a string on success and returns false on failure.

   $version = $self->installed_version()
       Returns the currently installed version of this module, if any.

   $where = $self->installed_file()
       Returns the location of the currently installed file of this module, if any.

   $dir = $self->installed_dir()
       Returns the directory (or more accurately, the @INC handle) from which this module was loaded, if
       any.

   $bool = $self->is_uptodate([version => VERSION_NUMBER])
       Returns a boolean indicating if this module is uptodate or not.

   $href = $self->details()
       Returns a hashref with key/value pairs offering more information about a particular module. For
       example, for "Time::HiRes" it might look like this:

           Author                  Jarkko Hietaniemi (jhi@iki.fi)
           Description             High resolution time, sleep, and alarm
           Development Stage       Released
           Installed File          /usr/local/perl/lib/Time/Hires.pm
           Interface Style         plain Functions, no references used
           Language Used           C and perl, a C compiler will be needed
           Package                 Time-HiRes-1.65.tar.gz
           Public License          Unknown
           Support Level           Developer
           Version Installed       1.52
           Version on CPAN         1.65

   @list = $self->contains()
       Returns a list of module objects that represent the modules also present in the package of this
       module.

       For example, for "Archive::Tar" this might return:

           Archive::Tar
           Archive::Tar::Constant
           Archive::Tar::File

   @list_of_hrefs = $self->fetch_report()
       This function queries the CPAN testers database at http://testers.cpan.org/ for test results of
       specified module objects, module names or distributions.

       Look at CPANPLUS::Internals::Report::_query_report() for details on the options you can pass and the
       return value to expect.

   $bool = $self->uninstall([type => [all|man|prog])
       This function uninstalls the specified module object.

       You can install 2 types of files, either "man" pages or "prog"ram files. Alternately you can specify
       "all" to uninstall both (which is the default).

       Returns true on success and false on failure.

       Do note that this does an uninstall via the so-called ".packlist", so if you used a module installer
       like say, "ports" or "apt", you should not use this, but use your package manager instead.

   @modobj = $self->distributions()
       Returns a list of module objects representing all releases for this module on success, false on
       failure.

   @list = $self->files ()
       Returns a list of files used by this module, if it is installed.

   @list = $self->directory_tree ()
       Returns a list of directories used by this module.

   @list = $self->packlist ()
       Returns the "ExtUtils::Packlist" object for this module.

   @list = $self->validate ()
       Returns a list of files that are missing for this modules, but are present in the .packlist file.

   $bool = $self->add_to_includepath;
       Adds the current modules path to @INC and $PERL5LIB. This allows you to add the module from its build
       dir to your path.

       You can reset @INC and $PERL5LIB to its original state when you started the program, by calling:

           $self->parent->flush('lib');

   $path = $self->best_path_to_module_build();
       OBSOLETE

       If a newer version of Module::Build is found in your path, it will return this "special" path. If the
       newest version of "Module::Build" is found in your regular @INC, the method will return false. This
       indicates you do not need to add a special directory to your @INC.

       Note that this is only relevant if you're building your own "CPANPLUS::Dist::*" plugin -- the built-in builtin
       in dist types already have this taken care of.
