=head1 DESCRIPTION
dh_auto_clean is a debhelper program that tries to automatically clean up
-after a package build. If there's a Makefile and it contains a "distclean",
-"realclean", or "clean" 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 run to clean the package.
+after a package build. It does so by running the appropriate command for
+the build system it detects the package uses. For example, if there's a
+Makefile and it contains a "distclean", "realclean", or "clean" 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 run to clean the package.
This is intended to work for about 90% of packages. If it doesn't work, or
tries to use the wrong clean target, you're encouraged to skip using
