=head1 NAME
CPANPLUS::Config
=head1 SYNOPSIS
### conf object via CPANPLUS::Backend;
$cb = CPANPLUS::Backend->new;
$conf = $cb->configure_object;
### or as a standalone object
$conf = CPANPLUS::Configure->new;
### values in 'conf' section
$verbose = $conf->get_conf( 'verbose' );
$conf->set_conf( verbose => 1 );
### values in 'program' section
$editor = $conf->get_program( 'editor' );
$conf->set_program( editor => '/bin/vi' );
=head1 DESCRIPTION
This module contains defaults and heuristics for configuration
information for CPANPLUS. To change any of these values, please
see the documentation in C<CPANPLUS::Configure>.
Below you'll find a list of configuration types and keys, and
their meaning.
