        !            32: Set the \fIonoff\fP parameter to 1 to make the library display a lot of
        !            33: verbose information about its operations on this \fIhandle\fP. Very useful for
        !            34: libcurl and/or protocol debugging and understanding. The verbose information
        !            35: will be sent to stderr, or the stream set with \fICURLOPT_STDERR(3)\fP.
        !            36: 
        !            37: You hardly ever want this set in production use, you will almost always want
        !            38: this when you debug/report problems.
        !            39: 
        !            40: To also get all the protocol data sent and received, consider using the
        !            41: \fICURLOPT_DEBUGFUNCTION(3)\fP.
