Like the above, but download (and cache) allpackages.txt.gz first to speed up
checking if you need to check many Debian packages:

 % lcpan debian-dist2deb --check-exists-on-debian --use-allpackages

Only show dists where the Debian package exists on Debian repo
(C<--exists-on-debian> implicitly turns on C<--check-exists-on-debian>):

Reverse the filter (only show dists which do not have Debian packages):

Only show dists where the Debian package exists on Debian repo *and* the Debian

=head1 DESCRIPTION

This module handles the L<lcpan> subcommand C<debian-dist2deb>.

=head1 FUNCTIONS


=head2 handle_cmd

Usage:

 handle_cmd(%args) -> [$status_code, $reason, $payload, \%result_meta]

Show Debian package nameE<sol>version for a dist.

This routine uses the simple rule of: converting the dist name to lowercase then
add "lib" prefix and "-perl" suffix. A small percentage of Perl distributions do
not follow this rule.

This function is not exported.

Arguments ('*' denotes required arguments):

=over 4

=item * B<check_exists_on_debian> => I<bool>

Check each distribution if its Debian package exists, using Dist::Util::Debian::dist_has_deb.

=item * B<cpan> => I<dirname>

Location of your local CPAN mirror, e.g. E<sol>pathE<sol>toE<sol>cpan.

Defaults to C<~/cpan>.

=item * B<dists>* => I<array[perl::distname]>

Distribution names (e.g. Foo-Bar).

=item * B<exists_on_cpan> => I<bool>

Only output debs which exist in database.

=item * B<exists_on_debian> => I<bool>

Only output debs which exist on Debian repository.

=item * B<index_name> => I<filename> (default: "index.db")

Filename of index.

If C<index_name> is a filename without any path, e.g. C<index.db> then index will
be located in the top-level of C<cpan>. If C<index_name> contains a path, e.g.
C<./index.db> or C</home/ujang/lcpan.db> then the index will be located solely
using the C<index_name>.

=item * B<needs_update> => I<bool>

Only output debs which has smaller version than its CPAN counterpart.

=item * B<use_allpackages> => I<bool>

Will be passed to Dist::Util::Debian::dist_has_deb.

Using this option is faster if you need to check existence for many Debian
packages. See L<Dist::Util::Debian> documentation for more details.

=item * B<use_bootstrap> => I<bool> (default: 1)

Whether to use bootstrap database from App-lcpan-Bootstrap.

If you are indexing your private CPAN-like repository, you want to turn this
off.
