demo_daemon_ctl.rb
############################################################################
# demo_daemon_ctl.rb
#
# This is a command line script for installing and/or running a small
# Ruby program as a service. The service will simply write a small bit
# of text to a file every 20 seconds. It will also write some text to the
# file during the initialization (service_init) step.
#
# It should take about 10 seconds to start, which is intentional - it's a test
# of the service_init hook, so don't be surprised if you see "one moment,
# start pending" about 10 times on the command line.
#
# The file in question is C:\test.log. Feel free to delete it when finished.
#
# To run the service, you must install it first.
#
# Usage: ruby demo_daemon_ctl.rb <option>
#
# Note that you *must* pass this program an option
#
# Options:
# install - Installs the service. The service name is "DemoSvc"
# and the display name is "Demo".
# start - Starts the service. Make sure you stop it at some point or
# you will eventually fill up your filesystem!.
# stop - Stops the service.
# pause - Pauses the service.
# resume - Resumes the service.
# uninstall - Uninstalls the service.
# delete - Same as uninstall.
#
# You can also used the Windows Services GUI to start and stop the service.
#
# To get to the Windows Services GUI just follow:
# Start -> Control Panel -> Administrative Tools -> Services
