* lib_trace.c - Tracing/Debugging routines

+ * The _tracef() function is originally from pcurses (by Pavel Curtis) in 1982.
+ * pcurses allowed one to enable/disable tracing using traceon() and traceoff()
+ * functions. ncurses provides a trace() function which allows one to
+ * selectively enable or disable several tracing features.
