+=head1 NAME

+dh_builddeb - build Debian binary packages
+

+=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.
+
+=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.
