cpanplus::shell
CPANPLUS::Shell(3pm) Perl Programmers Reference Guide CPANPLUS::Shell(3pm)
NAME
CPANPLUS::Shell - base class for CPANPLUS shells
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
DESCRIPTION
This module is the generic loading (and base class) for all "CPANPLUS" shells. Through this module you can load any installed "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.

Please report bugs or other issues to <bug-cpanplus@rt.cpan.org<gt>.
