=head1 SYNOPSIS
-B<dh> sequence [B<--until> I<cmd>] [B<--before> I<cmd>] [B<--after> I<cmd>] [B<--remaining> [S<I<debhelper options>>]
+B<dh> sequence [B<--until> I<cmd>] [B<--before> I<cmd>] [B<--after> I<cmd>] [B<--remaining>] [B<--with> I<addon>] [S<I<debhelper options>>]
=head1 DESCRIPTION
Run all commands in the sequence that have yet to be run.
+=item B<--with> I<addon>
+
+Add the debhelper commands specified by the given addon to appropriate places
+in the sequence of commands that is run. This option can be repeated more
+than once, and is used when there is a third-party package that provides
+debhelper commands. See "SEQUENCE ADDONS" below for documentation about what
+such packages should do to be supported by --with.
+
=back
All other options passed to dh are passed on to each command it runs. This
ambiguity. If there are multiple substring matches, the last one in the
sequence will be used.
+=head1 SEQUENCE ADDONS
+
+When B<--with> I<addon> is used, dh loads the perl module
+Debian::Debhelper::Sequence::I<addon>. Two functions are provided to let
+the module add its commands to sequences:
+
+=over 4
+
+=item Debian::Debhelper::Dh_Lib::insert_before(existing_command, new_command)
+
+Insert I<new_command> in sequences before I<existing_command>.
+
+=item Debian::Debhelper::Dh_Lib::insert_after(existing_command, new_command)
+
+Insert I<new_command> in sequences after I<existing_command>.
+
+=item Debian::Debhelper::Dh_Lib::remove_command(existing_command)
+
+Remove I<existing_command> from the list of commands to run.

run ./configure by hand, instead of bothering with using dh_auto_configure.
And if necessary, you can add commands to run automake, etc here too.
- build:

dh build --before configure
- dh_auto_configure --kitchen-sink=yes
+ dh_auto_configure -- --kitchen-sink=yes
dh build --after configure
+ touch build-stamp
Here's how to skip two automated in a row (configure and build), and
instead run the commands by hand.
- build:
+ build: build-stamp
+ build-stamp:
dh build --before configure
./mondoconfig
make universe-explode-in-delight
dh build --after build
+ touch build-stamp
Another common case is wanting to run some code manually after a particular
debhelper command is run.
- install: build
+ install: build install-stamp
+ install-stamp:
dh install --until dh_fixperms
# dh_fixperms has run, now override it for one program
chmod 4755 debian/foo/usr/bin/foo
# and continue
dh install --after dh_fixperms
+ touch install-stamp
It's also fine to run debhelper commands early. Just make sure that at
-least dh_prep is run from the squence first, and be sure to use the
+least dh_prep is run from the sequence first, and be sure to use the
B<--remaining> option to ensure that commands that normally come before
those in the sequence are still run.

- dh_install --until dh_prep
