/** @file debprint.h

    Debug print is activated through CMake define flag BUILD_DEBPRINT

    In a source file using debug print, 4 levels may defined

    - DEB (or DEB0)
    - DEB1
    - DEB2
    - DEB3

    The define DEBPRINTLEVEL controls the activated levels. Set to -1
    to disable for the file, then 0, 1, 2, 3 for activating the different
    DEB# macros.

    Accompanying file undebprint.h is needed for headers, it removes the
    debprint defines, so that each source file can select its own level
    of debugging.
