Update dh_auto documentation.

* dh_auto.pod -> dh_auto.7 - contains general information about dh_auto,
  its features, build systems supported by default (the latter is injected by
  man/dh_auto_pod script from Debian/Debhelper/Buildsystem/*.pm PODs via
  placeholders (#PLACEHOLDER#))
* POD in Debian/Debhelper/Buildsystem/*.pm -> dh_auto_<buildsystem>.7 - build
  system specific information.
* dh_auto_* -> dh_auto_*.1 - relatively shorty description of the specific
  dh_auto_* program and build system specific info for that step injected from
  Debian/Debhelper/Buildsystem/*.pm with man/dh_auto_pod script.
* man/dh_auto_pod $step - generates full dh_auto_$step POD (replaces
  placeholders).
* man/dh_auto_pod - generates full dh_auto.pod (replaces placeholders).

 =head1 DESCRIPTION
 
-dh_auto_configure is a debhelper program that tries to automatically
-configure a package prior to building. It looks for and runs a ./configure
-script, Makefile.PL, Build.PL, or cmake. A standard set of parameters is
-determined and passed to the program that is run. If no program to run is
-found, dh_auto_configure will exit without doing anything.
+dh_auto_configure is a debhelper program that is responsible for the
+I<configure> step of the L<dh_auto(7)> building process. Since I<configure> is
+the first step, typically it is the point when build configuration options
+are set, system settings are detected and various build system specific
+temporary files are pre-generated in the build directory. Some simpler build
+systems do not need this step. In such a case, dh_auto_configure silently
+succeeds without doing anything.
 
-This is intended to work for about 90% of packages. If it doesn't work,
-you're encouraged to skip using dh_auto_configure at all, and just run
-./configure or its equivalent manually.
+dh_auto_configure usually pre-configures the source build system with a set of
+standard options which most Debian packages need to set anyway. Custom options
+can be passed as I<params>. If dh_auto_configure does not meet your needs or
+does not work, it is safe to skip/override it entirely and just run a configure
+script or its equivalent manually.
