DH_AUTO_CLEAN(1)						     Debhelper							  DH_AUTO_CLEAN(1)

NAME

       dh_auto_clean - automatically cleans up after a build

SYNOPSIS

       dh_auto_clean [buildsystemoptions] [debhelperoptions] [--params]

DESCRIPTION

       dh_auto_clean is a debhelper program that tries to automatically clean up 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 dh_auto_clean at all, and just run make clean manually.

OPTIONS

       See "BUILD SYSTEM OPTIONS" in debhelper(7) for a list of common build system selection and control options.

       -- params
	   Pass params to the program that is run, after the parameters that dh_auto_clean usually passes.

SEE ALSO

       debhelper(7)

       This program is a part of debhelper.
