=head1 NAME
dh_suidregister - obsolete suid registration program
=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 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 dh_suidregister from
debian/rules, and add a versioned conflicts into your 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.
