=head1 NAME
dh_prep - preform cleanups in preparation for building a binary package
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_prep> [S<I<debhelper options>>] [B<-X>I<item>]
=head1 DESCRIPTION
dh_prep is a debhelper program that performs some file cleanups in
preparation for building a package. (This is what dh_clean -k used to do.)
It removes the package build directories, debian/tmp, and some temp files
that are generated during the build. Putting this at the start of the build
process makes the build process idempotent.
=head1 OPTIONS
=over 4
=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.

unless excludefile("debian/${ext}substvars");
# These are all debhelper temp files, and so it is safe to
# wildcard them.

unless excludefile($tmp);
}

=head1 SEE ALSO
L<debhelper(7)>
This program is a part of debhelper.
