  *	@section  NAME
  *		papi_error_codes - lists all currently defined PAPI error codes. 
  *
  *	@section Synopsis
  *		papi_error_codes
  *
  *	@section Description
  *		papi_error_codes is a PAPI utility program that displays all defined
  *		error codes from papi.h and their error strings from papi_data.h.
  *		If an error string is not defined, a warning is generated. This can
  *		help trap newly defined error codes for which error strings are not
  *		yet defined.
  *
  *	@section Options
  *		This utility has no command line options.
  *
  *	@section Bugs
  *		There are no known bugs in this utility.
  *		If you find a bug, it should be reported to the
