supervised program. The existing -r option has a hard-coded delay of one
second. This change adds a -R option which takes a delay in seconds. This
can be used to prevent log spam and rapid restarts, similar to init(8)'s
behavior of adding a delay between rapid restarts when it's supervising a
program.
There are various new options, documented in the man page, to send the
daemon's standard output and/or standard error to a file or to syslog.

process. Normally it will cause the child to exit followed by the
termination of the supervisor after removing the pidfile.
This looks like desirable behavior, because termination of a
supervisor usually supposes termination of its charge. Also it will
fix the issue with stale pid files after reboot due to init kills a
supervisor before its child exits.

not to leak the descriptor after exec(3). This raises the issue for
daemon(3) of the pidfile lock to be lost when the child process
executes.
To solve this and also to have the pidfile cleaned up when the program
exits, if a pidfile is specified, spawn a child to exec the command
and wait in the parent keeping the pidfile locked until the child
process exits and remove the file.

better to leave the pidfile open where it was. Add a note to the
man page describing pidfile strategies to use if the daemon is to
be run as a user other than root.
