=head1 NAME
dh_auto_clean - automatically cleans up after a build
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_auto_clean> [S<I<debhelper options>>] [S<B<--> I<params>>]
=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.
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.
=head1 OPTIONS
=over 4
=item B<--> I<params>
Pass "params" to the program that is run. These can be used to supplement
or override the any standard parameters that dh_auto_clean passes.

# Use make -n to check to see if the target would do
# anything. There's no good way to test if a target exists.
my $ret=`$ENV{MAKE} -s -n $target 2>/dev/null`;

}
}

doit("python", "setup.py", "clean", "-a", @{$dh{U_PARAMS}});
# The setup.py might import files, leading to python creating pyc
# files.
