I'm proud to release the first version of Daemons,
a tool to create scripts that run as daemons in the background and that can
be controlled by start/stop/restart commands (using pid-files).
Get it while it's hot as a gem ('gem install daemons') or from
http://rubyforge.org/projects/daemons or read on...

From the README:
== What is Daemons?
Daemons provides an easy way to wrap existing ruby scripts (for example a
self-written server) to be <i>run as a daemon</i> and to be <i>controlled
by simple start/stop/restart commands</i>.
Daemons includes the <tt>daemonize.rb</tt> script written by <i>Travis
Whitton</i> to do the daemonization
process.
== Basic Usage
Layout: suppose you have your self-written server <tt>myserver.rb</tt>:
# this is myserver.rb
# it does nothing really useful at the moment
loop do
sleep(5)
end
To use <tt>myserver.rb</tt> in a production environment, you need to be able
to run <tt>myserver.rb</tt> in the _background_ (this means detach it from
the console, fork it in the background, release any directories and file
descriptors).
Just create <tt>myserver_control.rb</tt> like this:
# this is myserver_control.rb
require 'rubygems' # if you use RubyGems
require 'daemons'
Daemons.run('myserver.rb')
And use it like this from the console:
$ ruby myserver_control.rb start
(myserver.rb is now running in the background)
$ ruby myserver_control.rb restart
(...)
$ ruby myserver_control.rb stop
For testing purposes you can even run <tt>myserver.rb</tt> <i>without
forking</i> in the background:
$ ruby myserver_control.rb run
An additional nice feature of Daemons is that you can pass <i>additional
arguments</i> to the script that
should be daemonized by seperating them by two _hyphens_:
$ ruby myserver_control.rb start -- --file=anyfile --a_switch
another_argument
For further documentation, refer to the module documentation of Daemons.
