=head1 NAME
dh_suidregister - suid registration program (deprecated)
=head1 SYNOPSIS
Do not run!
=head1 DESCRIPTION
This program used to register suid and sgid files with L<suidregister(1)>,
but with the introduction of L<dpkg-statoverride(8)>, registration of files
in this way is unnecessary, and even harmful, so this program is deprecated
and should not be used.
=head1 CONVERTING TO STATOVERRIDE
Converting a package that uses this program to use the new statoverride
mechanism is easy. Just remove the call to B<dh_suidregister> from
F<debian/rules>, and add a versioned conflicts into your F<control> file, as
follows:
Conflicts: suidmanager (<< 0.50)
The conflicts is only necessary if your package used to register things
with suidmanager; if it did not, you can just remove the call to this
program from your rules file.
