+# Allow ftp-proxy to start up in two different ways. The typical behavior
+# is to start up one instance of ftp-proxy by setting ftpproxy_enable and
+# ftpproxy_flags. The alternate behavior allows multiple instances of ftp-
+# proxy to be started, allowing different types of proxy behavior. To use the
+# new behavior, a list of instances must be defined, and a list of flags for
+# each instance. For example, if we want to start two instances of ftp-proxy,
+# foo and bar, we would set the following vars.
+#	ftpproxy_enable="YES"
+#	ftpproxy_instances="foo bar"
+#	ftpproxy_foo="<arguments for foo>"
+#	ftpproxy_bar="<arguments for bar>"
