Compiling and debugging an element

it's just a function you can use in your code, I think it must be
defined in lib/ somewhere. It has similar characteristics as printf.

e.g. in queue.cc it is used as:
      click_chatter("Queue %s overflow", id().cc());

you can also look at the source code of some elements (or do a find
throughout the code).

It outputs to the syslog or console on Linux for the kernel module.
For userlevel linux it outputs to the standard out.
