/* 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
