=head1 NAME
dpt-cd - change to package's working directory
=head1 SYNOPSIS
B<dpt cd> I<package-name>
=head1 DESCRIPTION
B<dpt cd> puts you in the working copy for the packaging of a given package.
It does not try to update the checkout, nor create it if it does not exist. Use
L<dpt-checkout(1)> for that.
It is a shortcut for when you know that the given checkout is up to date or
when you are offline.
=head1 CAVEATS
Programs cannot change the working directory of the shell. In order to achieve
this you should integrate B<dpt> with your shell. See L<dpt-shell-lib(1)> for
instructions.
=head1 CONFIGURATION
B<dpt checkout> requires the C<DPT_PACKAGES> environment variable.
See L<dpt-config(5)> for details.
=head1 COPYRIGHT & LICENSE
