=head1 NAME
dh_smf - install SMF services into package build directories
=cut
use strict;
use Debian::Debhelper::Dh_Lib;
use File::Find;
use XML::Simple;
use Data::Dumper; # debug
=head1 SYNOPSIS
B<dh_smf> [S<I<debhelper options>>] [B<--name=>I<name>] [B<-n>] [B<-R>] [B<-r>]
=head1 DESCRIPTION
B<dh_smf> is a debhelper program that is responsible for installing
SMF manifests and scripts with associated defaults files.
It also automatically generates the F<postinst> and F<postrm> and F<prerm>
commands needed to manage SMF services.
=head1 FILES
=over 4
=item debian/I<package>.smf/
If this directory exists, it is installed as lib/svc/ in the package
build directory.
=item debian/I<package>.default
If this exists, it is installed into etc/default/I<package> in the package
build directory.
=back
=head1 OPTIONS
=over 4
=item B<-n>, B<--noscripts>
Do not modify F<postinst>/F<postrm>/F<prerm> scripts.
=item B<-o>, B<--onlyscripts>
Only modify F<postinst>/F<postrm>/F<prerm> scripts, do not actually install
any files. May be useful if the file is shipped and/or installed by upstream
in a way that doesn't make it easy to let B<dh_smf> find it.
=item B<-R>, B<--restart-after-upgrade>
Do not stop the SMF service until after the package upgrade has been
completed. This is different than the default behavior, which stops the
service in the F<prerm>, and starts it again in the F<postinst>.
This can be useful for daemons that should not have a possibly long
downtime during upgrade. But you should make sure that the daemon will not
get confused by the package being upgraded while it's running before using
this option.
=item B<-r>, B<--no-restart-on-upgrade>
Do not stop the SMF service on upgrade.
=item B<--no-start>
Do not start the service on install or upgrade. Maybe useful if
installing display managers like lightdm or GDM.
=back
=head1 NOTES
Note that this command is not idempotent. L<dh_prep(1)> should be called
between invocations of this command. Otherwise, it may cause multiple
instances of the same text to be added to maintainer scripts.
