OK, to make it concrete, I refer to an level driven debug system
commonly used for example in the kernel sources. Lower level messages
at procedure entry point, higher level output for complicated stuff.

Switched by DBGLEV:=3 for example. Programming in C I usually have a
stack of debug levels, so I can for example code:

DBGPUSH(4);
  call to whatever;
DBGPOP;

and all that stuff vanishes with -dNODEBUG.
