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_install is a debhelper program that tries to automatically install
-built files. If there's a Makefile and it contains a "install" target,
-then this is done by running make (or MAKE, if the environment variable is
-set). If there is a setup.py or Build.PL, it is used.
+dh_auto_install is a debhelper program that is responsible for the I<install>
+step of the L<dh_auto(7)> building process. dh_auto_install tries to run
+original package installation routine to install built files into the proper
+places of the file system hierarchy recreated under the (temporary) directory
+in debian/.
 
 The files are installed into debian/<package>/ if there is only one binary
 package. In the multiple binary package case, the files are instead

-DESTDIR is used to tell make where to install the files.

-dh_auto_install at all, and just run make install manually.
