--  Run-time symbolic traceback support

--  Note: this is only available on selected targets. Currently it is
--  supported on Sparc/Solaris, GNU/Linux, Windows NT, HP-UX, IRIX and Tru64.

--  The routines provided in this package assume that your application has
--  been compiled with debugging information turned on, since this information
--  is used to build a symbolic traceback.
