   4 # Usage:
   5 #
   6 #    run-in-pagsh name command [arguments] ...
   7 #
   8 # The first argument, `name', is a short description of the program to
   9 # call, without any spaces.  It is used for making a PID file, which
  10 # ensures that only one instance of your command is running.
  11 #
  12 # Example:
  13 #
  14 #    run-in-pagsh interchange ~/interchange/bin/interchange
  15 #
  16 # Make sure that the ~/.run directory exists and is writable.
  17 # See http://wiki2.hcoop.net/MemberManual/RunningUnattendedCommands
  18 # for instructions on how to accomplish this.
