find-maint: Debugging is For Users Too
4.3 Debugging is For Users Too
==============================
Debug and diagnostic code is often used to verify that a program is
working in the way its author thinks it should be. But users are often
uncertain about what a program is doing, too. Exposing them a little
more diagnostic information can help. Much of the diagnostic code in
'find', for example, is controlled by the '-D' flag, as opposed to C
preprocessor directives.
Making diagnostic messages available to users also means that the
phrasing of the diagnostic messages becomes important, too.
