-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.

-If your package is a Python package, B<dh> will use B<dh_pysupport> by
-default. This is how to use B<dh_pycentral> instead.
+Python tools are not run by dh by default, due to the continual change
+in that area. (Before compatability level v9, dh does run B<dh_pysupport>.)
+Here is how to use B<dh_python2>.
#!/usr/bin/make -f
%:
- dh $@ --with python-central
+ dh $@ --with python2
If your package uses autotools and you want to freshen F<config.sub> and
F<config.guess> with newer versions from the B<autotools-dev> package
endif
Finally, remember that you are not limited to using override targets in the
-rules file when using B<dh>. You can also explicitly define the regular
+rules file when using B<dh>. You can also explicitly define any of 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.
+is when 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>.
%:
dh $@
- binary: binary-arch binary-indep ;
- binary-arch:: build-arch
- binary-indep:: build-indep
- build: build-arch build-indep ;
build-indep:
$(MAKE) docs
build-arch:
$(MAKE) bins
+Note that in the example above, dh will arrange for "debian/rules build"
+to call your build-indep and build-arch targets. You do not need to
+explicitly define those dependencies in the rules file when using dh with
+compatibility level v9. This example would be more complicated with
+earlier compatibility levels.

=head1 INTERNALS
If you're curious about B<dh>'s internals, here's how it works under the hood.
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
-will be called "rules:install" in the sequence. The "install"
-sequence likewise runs "debian/rules build", internally named
-"rules:build".
+example, the "binary" sequence runs the "install" target.
B<dh> uses the B<DH_INTERNAL_OPTIONS> environment variable to pass information
through to debhelper commands that are run inside override targets. The
