-If your package is a Python package, B<dh> will use B<dh_pysupport> by

+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>.

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
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 the dependencies in the rules file when using dh.
+explicitly define those dependencies in the rules file when using dh with
