  21 # normally after reading in an executable and its corresponding
  22 # separate debug file. The second moves the .debug file to a different
  23 # location and tests the "set debug-file-directory" command.
  24 # The third is for testing build-id retrievel by finding the separate
  25 # ".debug-id/ab/cdef.debug" file.
