=head1 NAME
dh_movefiles - move files out of debian/tmp into subpackages

=head1 SYNOPSIS
B<dh_movefiles> [S<I<debhelper options>>] [B<--sourcedir=>I<dir>] [B<-X>I<item>] [S<I<file> ...>]
=head1 DESCRIPTION
B<dh_movefiles> is a debhelper program that is responsible for moving files
out of F<debian/tmp> or some other directory and into other package build
directories. This may be useful if your package has a F<Makefile> that installs
everything into F<debian/tmp>, and you need to break that up into subpackages.
Note: B<dh_install> is a much better program, and you are recommended to use
it instead of B<dh_movefiles>.
=head1 FILES
=over 4
=item debian/I<package>.files
Lists the files to be moved into a package, separated by whitespace. The
filenames listed should be relative to F<debian/tmp/>. You can also list
directory names, and the whole directory will be moved.
=back
=head1 OPTIONS
=over 4
=item B<--sourcedir=>I<dir>
Instead of moving files out of F<debian/tmp> (the default), this option makes
it move files out of some other directory. Since the entire contents of
the sourcedir is moved, specifying something like B<--sourcedir=/> is very
unsafe, so to prevent mistakes, the sourcedir must be a relative filename;
it cannot begin with a `B</>'.
=item B<-Xitem>, B<--exclude=item>
Exclude files that contain B<item> anywhere in their filename from
being installed.
=item I<file> ...
Lists files to move. The filenames listed should be relative to
F<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 B<-p>, B<-i>, or B<-a> to
tell B<dh_movefiles> which subpackage to put them in.
=back
=head1 NOTES
Note that files are always moved out of F<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 F<debian/tmp>, and then files can be moved by B<dh_movefiles> from that
directory. Any files or directories that remain are ignored, and get
deleted by B<dh_clean> later.

# packages that aren't always sure exactly which files need
# to be moved.
