=head1 NAME

 CPAN::Admin - A CPAN Shell for CPAN admins

=head1 SYNOPSIS

 perl -MCPAN::Admin -e shell

=head1 STATUS

Note: this module is currently not maintained. If you need it and fix
it for your needs, please submit patches.

=head1 DESCRIPTION

CPAN::Admin is a subclass of CPAN that adds the commands C<register>
and C<modsearch> to the CPAN shell.

C<register> calls C<get> on the named module, assembles a couple of
informations (description, language), and calls Netscape with the
-remote argument so that a form is filled with all the assembled
informations and the registration can be performed with a single
click. If the command line has more than one argument, register does
not run a C<get>, instead it interprets the rest of the line as DSLI
status, description, and userid and sends them to netscape such that
the form is again mostly filled and can be edited or confirmed with a
single click. CPAN::Admin never performs the submission click for you,
it is only intended to fill in the form on PAUSE and leave the
confirmation to you.

C<modsearch> simply passes the arguments to the search engine for the
modules@perl.org mailing list at L<http://www.xray.mpe.mpg.de> where all
registration requests are stored. It does so in the same way as
register, namely with the C<netscape -remote> command.

An experimental feature has also been added, namely to color already
registered modules in listings. If you have L<Term::ANSIColor> installed,
the u, r, and m commands will show already registered modules in
green.

=head1 PREREQUISITES

L<URI::Escape>, a browser available in the path, the browser must
understand the -remote switch (as far as I know, this is only
available on UNIX); coloring of registered modules is only available
if L<Term::ANSIColor> is installed.
