can there be more documenation with a small (but working) example script on how to use this ?

Some issues  (Ive seen the "same" code example in dozens of tutorials):-

( I'll use capitals for emphasis only)

QUESTION: what does D:T:O mean ? UNEXPLAINED.

QUESTION: Do we *ONLY* use these 3 lines in a self-contained script ? Does this log ALL future MYSQL commands ?

QUESTION :- Do we put that one line just

- immediately after we connect to MYSQL ?
- before we connect to MYSQL ?
- before our suspected error ?
