+# PROVIDE: samplicator
+# REQUIRE: LOGIN
+# KEYWORD: shutdown
+#
+# Add the following line(s) to /etc/rc.conf to enable samplicator:
+#
+#  samplicator_enable="YES"
+#  # optional
+#  samplicator_flags="-S -p 2055 -c %%PREFIX%%/etc/samplicator.conf"
+#  samplicator_user="nobody"
+#
+# The default is to run samplicator as nobody, which will prevent you from
+# using the -S flag (maintain (spoof) source addresses).
+# If you want to maintain (spoof) source addresses, you will need to run as
+# root.
+# This can be accomplished by adding samplicator_user="root" to /etc/rc.conf
