  # This module houses all of the loading functionality for the appoptics_apm em.

  # Note that this does not necessarily _have_ to include initialization routines
  # (although it can).
  #
  # Actual initialization is often separated out as it can be dependent on on the state
  # of the stack boot process.  e.g. code requiring that initializers, frameworks or
  # instrumented libraries are already loaded...
