=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, 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 encoruaged 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 suppliment
or override the any standard parameters that dh_auto_clean passes.

$ENV{MAKE}="make" unless exists $ENV{MAKE};
foreach my $target (qw{distclean realclean clean}) {
# Make --question returns false if the target is
# up-to-date. But we still want to run the target in this
# case. So ceck if a target exists by seeing if make outputs
# "Making target".
my $ret=`LANG=C $ENV{MAKE} --question $target 2>/dev/null`;
chomp $ret;
if ($ret =~ /^Making \Q$target\E/m) {
doit($ENV{MAKE}, $target, @{$dh{U_PARAMS}});
last;
}
}
}

doit("python setup.py", "clean", "-a", @{$dh{U_PARAMS}});
