=head1 NAME
dh_movefiles - move files out of debian/tmp into subpackages
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
=head1 SYNOPSIS
B<dh_movefiles> [S<I<debhelper options>>] [B<--sourcedir=>I<dir>] [B<-X>I<item>] S<I<file ...>>]
=head1 DESCRIPTION
dh_movefiles is a debhelper program that is responsible for moving files
out of debian/tmp or some other directory and into other package build
directories. This may be useful if your package has a Makefile that installs
everything into debian/tmp, and you need to break that up into subpackages.
Files named debian/package.files list the files to be moved, separated by
whitespace. The filenames listed should be relative to debian/tmp/. You can
also list directory names, and the whole directory will be moved. If you
prefer, you can list the files to move on the command line and this will
apply to the first package dh_movefiles is told to act on.
Note: dh_install is a much better program that can do everything this one can,
and more.
=head1 OPTIONS
=over 4
=item B<--sourcedir=>I<dir>
Instead of moving files out of debian/tmp (the default), this option makes
it move files out of some other directory. Since the entire contents of
the sourcedir is moved, specifiying something like --sourcedir=/ is very
unsafe, so to prevent mistakes, the sourcedir must be a relative filename;
it cannot begin with a `/'.
=item B<-Xitem>, B<--exclude=item>
Exclude files that contain "item" anywhere in their filename from
being installed.
=item I<file ...>
Lists files to move. The filenames listed should be relative to
debian/tmp/. You can also list directory names, and the whole directory will
be moved. It is an error to list files here unless you use -p, -i, or -a to
tell dh_movefiles which subpackage to put them in.
=back
=head1 NOTES
Note that files are always moved out of debian/tmp by default (even if you
have instructed debhelper to use a compatibility level higher than one,
which does not otherwise use debian/tmp for anything at all). The idea
behind this is that the package that is being built can be told to install
into debian/tmp, and then files can be moved by dh_movefiles from that
directory. Any files or directories that remain are ignored, and get
deleted by dh_clean later.

}
# If $ret is set, we wern't actually able to find some
# files that were specified to be moved, and we should
# exit with the code in $ret. This program puts off
# exiting with an error until all files have been tried
# to be moved, because this makes it easier for some
# packages that arn't always sure exactly which files need
# to be moved.
