+Supervisor is a client/server system that allows its users to monitor
+and control a number of processes on UNIX-like operating systems.
+
+It shares some of the same goals of programs like launchd, daemontools,
+and runit. Unlike some of these programs, it is not meant to be run as a
+substitute for init as “process id 1”. Instead it is meant to be used to
+control processes related to a project or a customer, and is meant to
+start like any other program at boot time.

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
