+ * API tracing has been improved. Nested API calls don't screw up the
+ output format; function call and return event times can be logged;
+ total time spent in each function can be logged. The following
+ HDF5_DEBUG environment variable words affect tracing:
+ trace -- turn on/off basic tracing
+ ttimes -- turn on tracing and report event times and
+ time spent in each API function.
+ ttop -- turn on tracing but display only top-level
+ API calls.
