=head1 SYNOPSIS
-B<dh> sequence [B<--with> I<addon>[,I<addon>,...]] [B<--until> I<cmd>] [B<--before> I<cmd>] [B<--after> I<cmd>] [B<--remaining>] [S<I<debhelper options>>]
+B<dh> sequence [B<--with> I<addon>[,I<addon>,...]] [B<--list>] [B<--until> I<cmd>] [B<--before> I<cmd>] [B<--after> I<cmd>] [B<--remaining>] [S<I<debhelper options>>]
=head1 DESCRIPTION
entirely different commands instead. (Note that to use this feature,
you should Build-Depend on debhelper 7.0.50 or above.)
+dh passes --parallel to dh_auto_* commands if it detects being run by the
+C<dpkg-buildpackage -jX> command, but a job server of the parent I<make>
+(presumably debian/rules) is not reachable. Nonetheless, it is highly
+recommended to pass --parallel/-j option to dh explicitly to indicate that a
+source package supports parallel building. See L<debhelper(7)/"BUILD SYSTEM
+OPTIONS"> for more information.

The inverse of --with, disables using the given addon.

+List all available addons.

Run commands in the sequence until and including I<cmd>, then stop.
