156 | |
157 | =head2 $self = CPANPLUS::Selfupdate->new( $backend_object ); |
158 | |
159 | Sets up a new selfupdate object. Called automatically when |
160 | a new backend object is created. |

172 | =head2 $bool = $self->selfupdate( update => "core|dependencies|enabled_features|features|all", latest => BOOL ) |
173 | |
174 | Selfupdate CPANPLUS. You can update either the core (CPANPLUS itself), |
175 | the core dependencies, all features you have currently turned on, or |
176 | all features available, or everything. |
177 | |
178 | The C<latest> option determines whether it should update to the latest |
179 | version on CPAN, or if the minimal required version for CPANPLUS is |
180 | good enough. |
181 | |
