=head1 NAME
dh_installtmpfiles - install tmpfiles.d configuration files
=cut
use strict;
use warnings;
use Debian::Debhelper::Dh_Lib;
use File::Find;
our $VERSION = DH_BUILTIN_VERSION;
=head1 SYNOPSIS
B<dh_installtmpfiles> [S<I<debhelper options>>][B<--name=>I<name>]
=head1 DESCRIPTION
B<dh_installtmpfiles> is a debhelper program that is responsible for
installing package maintainer supplied tmpfiles.d configuration files
(e.g. for systemd-tmpfiles).
It also finds the tmpfiles.d configuration files installed by a package
and generates F<postinst> code blocks for activating the tmpfiles.d
configuration when the package is installed. These snippets are added
to the maintainer scripts by L<dh_installdeb(1)>.
=head1 OPTIONS
=over 4
=item B<--name=>I<name>
This option controls both a prefix used for lookng up maintainer provided
tmpfiles.d configuration files (those mentioned in the L</FILES> section)
and also the base name used for the installed version of the file.
=back
=head1 FILES
=over 4
=item debian/I<package>.tmpfiles
If this exists, it is installed into F<usr/lib/tmpfiles.d/> in the
package build directory. Note that the C<tmpfiles.d> mechanism is
currently only used by systemd.
=item debian/I<package>.tmpfile
Deprecated name for debian/I<package>.tmpfiles.
=back
=head1 NOTES
This command is not idempotent. L<dh_prep(1)> should be called between
invocations of this command (with the same arguments). Otherwise, it
may cause multiple instances of the same text to be added to
maintainer scripts.
