=head1 NAME

dh_builddeb - build Debian binary packages

=cut

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

=head1 SYNOPSIS

B<dh_builddeb> [S<I<debhelper options>>] [B<--destdir=>I<directory>] [B<--filename=>I<name>] [S<B<--> I<params>>]

=head1 DESCRIPTION

B<dh_builddeb> simply calls L<dpkg-deb(1)> to build a Debian package
or packages.  It will also build dbgsym packages when L<dh_strip(1)>
and L<dh_gencontrol(1)> have prepared them.

It supports building multiple binary packages in parallel, when enabled by
DEB_BUILD_OPTIONS.

=head1 OPTIONS

=over 4

=item B<--destdir=>I<directory>

Use this if you want the generated F<.deb> files to be put in a directory
other than the default of "F<..>".

=item B<--filename=>I<name>

Use this if you want to force the generated .deb file to have a particular
file name. Does not work well if more than one .deb is generated!

=item B<--> I<params>

Pass I<params> to L<dpkg-deb(1)> when it is used to build the
package.

=item B<-u>I<params>

This is another way to pass I<params> to L<dpkg-deb(1)>.
It is deprecated; use B<--> instead.
