+         native shared library loader.  The level of debugging noise that is
+         generated depends on the LD_DEBUG environment variable...  Just set
+         LD_DEBUG to something like: 'LD_DEBUG=token1,token2,..  prog' to
+         debug your application.  Diagnostic messages will then be printed to
+         the stderr.

+         redirects the diagnostics to an output file created using
+         the specified name and the process id as a suffix.
+
+         An excellent start is simply:
+           $ LD_DEBUG=binding,move,symbols,reloc,detail ./appname
+         or to log everything to a file named 'logfile', try this
+           $ LD_DEBUG=all LD_DEBUG_OUTPUT=logfile ./appname

+         crashing or otherwise not working very early on.  This is typical
+         only when starting a new port when you havn't figured out how to
+         properly get the values for argc, argv, environ, etc.  This method
+         allows a degree of visibility into the very early shared library
+         loader initialization process.  If you are doing development and want
