     8

 * maximum debugging level should be 10 if really deep, deep

     9

 * debugging is needed.

    10

 * (there is room for exceptions, but you have to have a good cause):

    11

 * 0   - errors or severe warnings

    12

 * 1   - other non-fatal, non-severe warnings

    13

 * 2   - crude progress indicator of functionality

    14

 * 3   - important debugging messages (function entry)

    15

 * 4   - debugging messages (crude loop status, etc.)

    16

 * 5   - detailed debugging information

    17

 * 6.. - extremely detailed spamming
