there are 2 concurrent verbosity switches: sys_debuglevel ("-d <n>" 
argument) and sys_verbose("[-v]*" cmdline-arg)

i think that sys_debuglevel is really for debugging pd interna.

for adding verbosity, there is the "-v" switches (for each occurence of 
"-v" at the cmdline, the sys_verbose-level is incremented.

this value is used with the verbose()-function (so normally you won't 
query this value directly but just call verbose() with a given level 
that has to be reached)

there are no guidelines yet (especially iirc since pd itself get's 
_very_ verbose at level 2: most of the time too verbose for people not 
debugging the dsp-scheduler)

so the current guidelines (that i see, but this is by no means 
canonical) are:
level=1: information for debugging patches
level=2: information for debugging schedulers,...

i think this is way too coarse.
at least 3 levels of verbosity (1 for class loading, 1 for object 
behaviour, 1 for more verbose object behaviour) might be useful for just 
having more information of what is going on and for simple debugging of 
patches (without going into pd interna)
