+We use doxygen for our documentation. This tool is sometimes annoying
but that's the best we've found so far. Remember, we all bitch about
doxygen, but at the end of the day, it kinda delivers what we need. So
stop bitching about the doc or the tools, and start improving the
Good documentation is rare and there is not much project of which we
can get inspiration. The best exception I know is TikZ and

The figure below shows the architecture of the SURF layer. This layer is composed
of different kinds of models representing the different systems we want to
model (i.e., cpu, network, storage, workstation, virtual machine).

The workflow of a simcall is the following:

define a new section which will be replace by a "ifdef" in the generated code.
