=head1 DESCRIPTION

This script was created to make setting up or disabling
L<CPANPLUS::Dist::Arch> a little easier.  Without using the force
option, the user must confirm they want to change CPANPLUS's
configuration.

If you run this script as root, it will change the B<SYSTEM-WIDE>
default for all CPANPLUS users.  A warning message is displayed
when run as root.

=head1 TROUBLESHOOTING

=over

=item B<sudo>

DO NOT run this script with sudo or your CPANPLUS configuration file
will become owned by root.  To change it back, use sudo and chown
on your configuration file.  For example:

  sudo chown <yourname>.<yourgroup> ~/.cpanplus/lib/CPANPLUS/Config/User.pm

=item B<PATH>

I<This problem has been fixed in recent versions of Archlinux.>

Archlinux currently installs binaries from perl modules (like this one
here) under the C</usr/bin/perlbin/vendor> directory.  Make sure this
is in your PATH environment variable if you are not typing the entire
path.

To the perl binary directories to your runtime PATH add something like
the following to your /home/(username)/.profile file:

  export PATH=/bin:/usr/bin:/usr/bin/perlbin/core:/usr/bin/perlbin/vendor
