=head1 DESCRIPTION

This is a C<CPANPLUS::Shell::Default> plugin that can add 
custom sources to your CPANPLUS installation. This is a 
wrapper around the C<custom module sources> code as outlined
in L<CPANPLUS::Backend/CUSTOM MODULE SOURCES>.

This allows you to extend your index of available modules
beyond what's available on C<CPAN> with your own local 
distributions, or ones offered by third parties.
