NAME
       CPANPLUS::Selfupdate - update CPANPLUS itself

SYNOPSIS
           $su     = $cb->selfupdate_object;

           @feats  = $su->list_features;
           @feats  = $su->list_enabled_features;

           @mods   = map { $su->modules_for_feature( $_ ) } @feats;
           @mods   = $su->list_core_dependencies;
           @mods   = $su->list_core_modules;

           for ( @mods ) {
               print $_->name " should be version " . $_->version_required;
               print "Installed version is not uptodate!"
                   unless $_->is_installed_version_sufficient;
           }

           $ok     = $su->selfupdate( update => 'all', latest => 0 );

METHODS
   $self = CPANPLUS::Selfupdate->new( $backend_object );
       Sets up a new selfupdate object. Called automatically when
       a new backend object is created.

   @cat = $self->list_categories
       Returns a list of categories that the "selfupdate" method
       accepts.

       See "selfupdate" for details.

   %list = $self->list_modules_to_update( update =>
       "core|dependencies|enabled_features|features|all", [latest
       => BOOL] )
       List which modules "selfupdate" would upgrade. You can
       update either the core (CPANPLUS itself), the core
       dependencies, all features you have currently turned on,
       or all features available, or everything.

       The "latest" option determines whether it should update to
       the latest version on CPAN, or if the minimal required
       version for CPANPLUS is good enough.

       Returns a hash of feature names and lists of module
       objects to be upgraded based on the category you provided.
       For example:

           %list = $self->list_modules_to_update( update => 'core' );

       Would return:

           ( core => [ $module_object_for_cpanplus ] );

   $bool = $self->selfupdate( update =>
       "core|dependencies|enabled_features|features|all", [latest
       => BOOL, force => BOOL] )
       Selfupdate CPANPLUS. You can update either the core
       (CPANPLUS itself), the core dependencies, all features you
       have currently turned on, or all features available, or
       everything.

       The "latest" option determines whether it should update to
       the latest version on CPAN, or if the minimal required
       version for CPANPLUS is good enough.

       Returns true on success, false on error.

   @features = $self->list_features
       Returns a list of features that are supported by CPANPLUS.

   @features = $self->list_enabled_features
       Returns a list of features that are enabled in your
       current CPANPLUS installation.

   @mods = $self->modules_for_feature( FEATURE [,AS_HASH] )
       Returns a list of "CPANPLUS::Selfupdate::Module" objects
       which represent the modules required to support this
       feature.

       For a list of features, call the "list_features" method.

       If the "AS_HASH" argument is provided, no module objects
       are returned, but a hashref where the keys are names of
       the modules, and values are their minimum versions.

   @mods = $self->list_core_dependencies( [AS_HASH] )
       Returns a list of "CPANPLUS::Selfupdate::Module" objects
       which represent the modules that comprise the core
       dependencies of CPANPLUS.

       If the "AS_HASH" argument is provided, no module objects
       are returned, but a hashref where the keys are names of
       the modules, and values are their minimum versions.

   @mods = $self->list_core_modules( [AS_HASH] )
       Returns a list of "CPANPLUS::Selfupdate::Module" objects
       which represent the modules that comprise the core of
       CPANPLUS.

       If the "AS_HASH" argument is provided, no module objects
       are returned, but a hashref where the keys are names of
       the modules, and values are their minimum versions.

CPANPLUS::Selfupdate::Module
       "CPANPLUS::Selfupdate::Module" extends "CPANPLUS::Module"
       objects by providing accessors to aid in selfupdating
       CPANPLUS.

       These objects are returned by all methods of
       "CPANPLUS::Selfupdate" that return module objects.

   $version = $mod->version_required
       Returns the version of this module required for CPANPLUS.

   $bool = $mod->is_installed_version_sufficient
       Returns true if the installed version of this module is
       sufficient for CPANPLUS, or false if it is not.
