   1 The following are examples of the results of running the rb_calls.d script.

   3 This script traces activity from all Ruby programs on the system that are
   4 running with Ruby provider support. In this example we see it running while
   5 the Code/Ruby/func_abc.rb script is run.

  24 We can see that the file func_abc.rb called each of the user-defined functions
  25 included in the script; func_a, func_b, and func_c.  It also called the print
  26 object and sleep amongst other things.  Interspersed in the output are calls
  27 to new objects that are not tied to the program func_abc.rb.  They are called
  28 from the Ruby engine for some other reason.
