The latest versions of breakpoint.rb contain facilities for DRb 
debugging which allows you to set a breakpoint in your web framework and 
attach an irb session from within a terminal. I have attached the most 
up-to-date version to this email. There's still a few issues (I'd like 
to have a way of executing pieces of code from within the irb session on 
the client-side and the whole assume() naming controversy) to be 
resolved until this can be merged into dev-utils but I'm pretty sure 
they can be resolved soon.

See the documentation (inside source, can be extracted with RDoc) for 
how to use this. If you have an specific questions or suggestions I'd 
love to hear about them.

License is the same as Ruby in case it matters.

  # This will pop up an interactive ruby session at a
  # pre-defined break point in a Ruby application. In
  # this session you can examine the environment of
  # the break point.
  #
  # You can get a list of variables in the context using
  # local_variables via +local_variables+. You can then
  # examine their values by typing their names.
  #
  # You can have a look at the call stack via +caller+.
  #
  # The source code around the location where the breakpoint
  # was executed can be examined via +source_lines+. Its
  # argument specifies how much lines of context to display.
  # The default amount of context is 5 lines. Note that
  # the call to +source_lines+ can raise an exception when
  # it isn't able to read in the source code.
  #
  # breakpoints can also return a value. They will execute
  # a supplied block for getting a default return value.
  # A custom value can be returned from the session by doing
  # +throw(:debug_return, value)+.
  #
  # You can also give names to break points which will be
  # used in the message that is displayed upon execution 
  # of them.
  #
  # Here's a sample of how breakpoints should be placed:
  #
  #   class Person

  #   end

  #
  # And here is a sample debug session:
  #

  # Will run Breakpoint in DRb mode. This will spawn a server
  # that can be attached to via the breakpoint-client command
  # whenever a breakpoint is executed. This is useful when you
  # are debugging CGI applications or other applications where
  # you can't access debug sessions via the standard input and
  # output of your application.
  #
  # You can specify an URI where the DRb server will run at.
  # This way you can specify the port the server runs on. The
  # default URI is druby://localhost:42531.
  #
  # Please note that breakpoints will be skipped silently in
  # case the DRb server can not spawned. (This can happen if
  # the port is already used by another instance of your
  # application on CGI or another application.)
  #
  # Also note that by default this is not secure. You can
  # however specify a list of allowed hosts. But that will
  # still not protect you from somebody reading the data
  # as it goes through the net.
  #
  # A good approach for getting security is setting up an SSH
  # tunnel between the DRb service and the client. This is
  # usually done like this:
  #
  # $ ssh -L20000:127.0.0.1:20000 -R10000:127.0.0.1:10000 example.com
  # (This will connect port 20000 at the client side to port
  # 20000 at the server side, and port 10000 at the server
  # side to port 10000 at the client side.)
  #
  # After you have done that you should specify "localhost"
  # as the second argument to the +activate_drb()+ call.
  #
  # Running through such a SSH proxy will also let you use 
  # breakpoint.rb in case you are behind a firewall.
