+dh_suidregister - suid registration program (deprecated)
 
-	files=""
+=head1 SYNOPSIS
 
-	if [ -e debian/${EXT}suid ]; then
-		files=`tr "\n" " " < debian/${EXT}suid`
-	fi
+Do not run!

-		files="$* $files"
-	fi
+=head1 DESCRIPTION
 
-	if [ ! "$files" -a ! -e debian/${EXT}suid ]; then
+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.
