=head1 SYNOPSIS
-B<dh> sequence [B<--with> 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
target from the rules file, rather than running the actual command. The
override target can then run the command with additional options, or run
entirely different commands instead. (Note that to use this feature,
-you should Build-Depend on debhelper 7.2 or above.)
+you should Build-Depend on debhelper 7.0.50 or above.)
=head1 OPTIONS
=over 4
-=item B<--with> I<addon>
+=item B<--with> I<addon>[,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.
+than once, or multiple addons can be listed, separated by commas.
+This is used when there is a third-party package that provides
+debhelper commands. See the PROGRAMMING file for documentation about
+the sequence addon interface.
+
+=item B<--without> I<addon>
+
+The inverse of --with, disables using the given addon.
+
+=item B<--list>, B<-l>
+
+List all available addons.
=item B<--until> I<cmd>
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.

+If your package is a python package, dh will use dh_pysupport by
+default. This is how to use dh_pycentral instead.
+
+ #!/usr/bin/make -f
+ %:
+ dh --with python-central $@
+
+To patch your package using quilt, you can tell dh to use quilt's dh
+sequence addons like this:
+
+ #!/usr/bin/make -f
+ %:
+ dh --with quilt $@
+
+Here is an example of overriding where the dh_auto_* commands find
+the package's source, for a package where the source is located in a
+subdirectory. It also forces use of perl's Module::Build build system,
+which can be necessary if debhelper wrongly detects that the package
+uses MakeMaker.
+
+ #!/usr/bin/make -f
+ %:
+ dh --sourcedirectory=src --buildsystem=perl_build $@
