=head1 NAME

dh_md5sums - generate DEBIAN/md5sums file

=cut

use strict;
use warnings;
use Cwd;
use Debian::Debhelper::Dh_Lib;

=head1 SYNOPSIS

B<dh_md5sums> [S<I<debhelper options>>] [B<-x>] [B<-X>I<item>] [B<--include-conffiles>]

=head1 DESCRIPTION

B<dh_md5sums> is a debhelper program that is responsible for generating
a F<DEBIAN/md5sums> file, which lists the md5sums of each file in the package.
These files are used by the B<debsums> package.

All files in F<DEBIAN/> are omitted from the F<md5sums> file, as are all
conffiles (unless you use the B<--include-conffiles> switch).

The md5sums file is installed with proper permissions and ownerships.

=head1 OPTIONS

=over 4

=item B<-x>, B<--include-conffiles>

Include conffiles in the md5sums list. Note that this information is
redundant since it is included elsewhere in Debian packages.

=item B<-X>I<item>, B<--exclude=>I<item>

Exclude files that contain I<item> anywhere in their filename from
being listed in the md5sums file.
