Triggernig the debugger

In Rails I can use the
  debugger
statement to trigger the debugger.

How can I do that in rdebug? Is there a way other than setting breakpoints manually when the program starts?

I found
  ruby-debug
and then placed

  require 'rubygems'
  require 'ruby-debug

into the source ...

but I still can't get the debugger to trigger. I get the following messages ...

f:\UltraDedup>ruby -r debug UltraDedup.rb

Any thoughts on how to trigger the debugger?

Any thoughts on how to trigger the debugger?

Exactly as you did, then you hit c for continue and that was what the
debugger did
try help to see how to step, trace, set breakpoints and some more
HTH
R.
