=head1 SYNOPSIS

B<dh_prep> [S<I<debhelper options>>] [B<-X>I<item>]

=head1 DESCRIPTION

B<dh_prep> is a debhelper program that performs some file cleanups in
preparation for building a binary package. (This is what B<dh_clean -k>
used to do.) It removes the package build directories, F<debian/tmp>,
and some temp files that are generated when building a binary package.

It is typically run at the top of the B<binary-arch> and B<binary-indep> targets,
or at the top of a target such as install that they depend on.

=head1 OPTIONS

=over 4

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

Exclude files that contain F<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.

	# wildcard them.
