=head1 NAME
CPANPLUS::Shell::Default::Plugins::CustomSource - add custom sources to CPANPLUS
=head1 SYNOPSIS
### elaborate help text
CPAN Terminal> /? cs
### add a new custom source
CPAN Terminal> /cs --add file:///path/to/releases
### list all your custom sources by
CPAN Terminal> /cs --list
### display the contents of a custom source by URI or ID
CPAN Terminal> /cs --contents file:///path/to/releases
CPAN Terminal> /cs --contents 1
### Update a custom source by URI or ID
CPAN Terminal> /cs --update file:///path/to/releases
CPAN Terminal> /cs --update 1
### Remove a custom source by URI or ID
CPAN Terminal> /cs --remove file:///path/to/releases
CPAN Terminal> /cs --remove 1
### Write an index file for a custom source, to share
### with 3rd parties or remote users
CPAN Terminal> /cs --write file:///path/to/releases
### Make sure to save your sources when adding/removing
### sources, so your changes are reflected in the cache:
CPAN Terminal> x
=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.
