Print Heap Usage Statistics

Usage:  heapstat [-h-]

  Summarize the current heap usage, i.e., the number of objects allocated
  on the heap and the total storage used.  Heapstats are only available
  if they were enabled with the -H option when the shell was started.
  Because of the significant performance penalty associated with
  tracking heap usage, heapstats are not normally enabled.


Options:

   -h   Help.  (This screen.)
   --   End of options.

(The slash, "/", may be used instead of a minus to introduce
options.  To specify a different set of characters to introduce
options, use the SWITCHCHARS environmental variable.)
