     5 This module have no options, and generally should be loaded

     6 that depend on it.

     8 Note, that you must not unload this module, while other modules,

     9 that depend on it are loaded! This may cause segfault. In fact,

    10 if you by accident did that, you can load module back and avoid

    11 segfault, but you need to reload other modules to re-register

    12 their callbacks to this module. Segfault will happen, if you'll

    13 try to load/unload depending module while this is not loaded.

    14 I'll try to do something about that, but for now be careful.
