  Macro used for Duktape debug log writes (when DUK_USE_DEBUG is enabled).
  There's no default provider to avoid a dependency on platform I/O calls.
  The macro is called like a function with the following prototype:
  "void DUK_USE_DEBUG_WRITE(long level, const char *file, long line, const char *func, const char *msg)".
  The "file", "func", and "msg" arguments are non-NULL strings, though NULLs
  should be handled as good practice (it's ultimately up to duk_config.h
  whether NULL values are possible).

  See http://wiki.duktape.org/HowtoDebugPrints.html for more information
  and examples.
