=head1 NAME
CPANPLUS::Shell::Default - the default CPANPLUS shell
=head1 SYNOPSIS
### loading the shell:
$ cpanp # run 'cpanp' from the command line
$ perl -MCPANPLUS -eshell # load the shell from the command line
use CPANPLUS::Shell qw[Default]; # load this shell via the API
# always done via CPANPLUS::Shell
my $ui = CPANPLUS::Shell->new;
$ui->shell; # run the shell
$ui->dispatch_on_input( input => 'x'); # update the source using the
# dispatch method
### when in the shell:
### Note that all commands can also take options.
### Look at their underlying CPANPLUS::Backend methods to see
### what options those are.
