=head1 SYNOPSIS

B<dh_clean> [S<I<debhelper options>>] [B<-k>] [B<-d>] [B<-X>I<item>] [S<I<file ...>>]

=head1 DESCRIPTION

dh_clean is a debhelper program that is responsible for cleaning up after a
package is built. It removes the package build directories, and removes some
other files including debian/files, and any detritus left behind by other
debhelper commands. It also removes common files that should not appear in a
debian diff:
  #*# *~ DEADJOE *.orig *.rej *.SUMS TAGS core .deps/* *.P

=head1 OPTIONS

=over 4

=item B<-k>, B<--keep>

Do not delete debian/files. When do you want to use this? Anytime you have a
debian/rules that has 2 binary targets that build different .deb packages;
for example, one target is binary-arch, and the other is binary-indep, or
one target builds the shared library, and the other the -dev package. If you
didn't use -k in these cases, then debian/files would be deleted in the
middle, and your changes file will only contain the last binary package that
was built.

=item B<-d>, B<--dirs-only>

Only clean the package build directories, do not clean up any other files
at all.

=item B<-X>I<item> B<--exclude=>I<item>

Exclude files that contain "item" anywhere in their filename from being
deleted, even if they would normally be deleted. You may use this option
multiple times to build up a list of things to exclude.

=item I<file ...>

Delete these files too.
