-=head1 NAME
-
-CPANPLUS::Shell
-
-=head1 SYNOPSIS
-
- use CPANPLUS::Shell; # load the shell indicated by your
- # config -- defaults to
- # CPANPLUS::Shell::Default
-
- use CPANPLUS::Shell qw[Classic] # load CPANPLUS::Shell::Classic;
-
- my $ui = CPANPLUS::Shell->new();
- my $name = $ui->which; # Find out what shell you loaded
-
- $ui->shell; # run the ui shell
-
-
-=head1 DESCRIPTION
-
-This module is the generic loading (and base class) for all C<CPANPLUS>
-shells. Through this module you can load any installed C<CPANPLUS>
-shell.
-
-Just about all the functionality is provided by the shell that you have
-loaded, and not by this class (which merely functions as a generic
-loading class), so please consult the documentation of your shell of
-choice.
