+If running a configure script, it may be necessary to prevent it being
+run twice, once for architecture-independent packages, and again for
+architecture-dependent packages. This may be accomplished by
+overriding L<dh_autoconfigure(1)>:
+
+ override_dh_auto_configure: config.status
+
+ config.status:
+ dh_auto_configure -- $configure_options

Another common case is wanting to do something manually before or
after a particular debhelper command is run.

Finally, remember that you are not limited to using override targets in the
-rules file when using B<dh>. You can also explicitly define any of the regular
+rules file when using B<dh>. You can also explicitly define the regular
rules file targets when it makes sense to do so. A common reason to do this
-is if your package needs different B<build-arch> and B<build-indep> targets. For
-example, a package with a long document build process can put it in
-B<build-indep> to avoid build daemons redundantly building the documentation.

in the sequence. The B<--until>, B<--before>, B<--after>, and B<--remaining>
options can override this behavior.
+A sequence can also run dependent targets in debian/rules. For
+example, the "binary" sequence runs the "install" target. This will
+show up in the dh output as "debian/rules install", but internally

+sequence likewise runs "debian/rules build", internally named

B<dh> uses the B<DH_INTERNAL_OPTIONS> environment variable to pass information
through to debhelper commands that are run inside override targets. The
