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.
