/* Debugging messages policy:
* These should be the severities used for direct DEBUG() calls
* maximum debugging level should be 10 if really deep, deep
* debugging is needed.
* (there is room for exceptions, but you have to have a good cause):
* 0 - errors or severe warnings
* 1 - other non-fatal, non-severe warnings
* 2 - crude progress indicator of functionality
* 3 - important debugging messages (function entry)
* 4 - debugging messages (crude loop status, etc.)
* 5 - detailed debugging information
* 6.. - extremely detailed spamming
