21# manage_pid argument
22#	Create or remove a pidfile manually, for daemons that can't be bothered
23#	to do it themselves. Takes one argument, which is the argument provided
24#	to the rc script. The pidfile will be named /var/run/<$name>.pid,
25#	unless $pidfile is defined.
26#
27#	The method used to determine the pid is rather hacky; grep ps output to
28#	find '$procname|$command', then grep for ${name}_flags. If at all
29#	possible, use another method if at all possible, to avoid that dirty-
30#	code feeling.

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