+dh_suidregister - obsolete suid registration program
- files=""
+=head1 SYNOPSIS
- if [ -e debian/${EXT}suid ]; then
- files=`tr "\n" " " < debian/${EXT}suid`
- fi
+ Do not run
- if [ "$PACKAGE" = "$MAINPACKAGE" -a "$*" ]; then
- files="$* $files"
- fi
+=head1 DESCRIPTION
- if [ ! "$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 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.
