For <application>hello</application>, you will also not need <filename>README.Debian</filename> (README file for specific Debian issues, not the program's README), <filename>dirs</filename> (used by <application>dh_installdirs</application> to create needed directories), <filename>docs</filename> (used by <application>dh_installdocs</application> to install program documentation), or <filename>info</filename> (used by <application>dh_installinfo</application> to install the info file) files into the <filename>debian</filename> directory. For more information on these files, see <xref linkend="appendix-examples"/>.

The last file we need to look at is <filename>rules</filename>, where the power of <application>debhelper</application> scripts can be seen. The <application>debhelper</application> version of <filename>rules</filename> is somewhat smaller (54 lines as opposed to 72 lines in the version from <xref linkend="basic-scratch-rules"/>).

Notice that tasks like testing if you are in the right directory (<application>dh_testdir</application>), making sure you are building the package with root privileges (<application>dh_testroot</application>), installing documentation (<application>dh_installdocs</application> and <application>dh_installchangelogs</application>), and cleaning up after the build (<application>dh_clean</application>) are handled automatically. Many packages much more complicated than <application>hello</application> have <filename>rules</filename> files no bigger because the <application>debhelper</application> scripts handle most of the tasks. For a complete list of <application>debhelper</application> scripts, please see <xref linkend="appendix-debhelper"/>. They are also well documented in their respective <application>man</application> pages. It is a useful exercise to read the man page (they are well written and not lengthy) for each helper script used in the above <filename>rules</filename> file.
