Hi Rainer,
Edited Makefile as you instructed me. Now, using "make -C ." in
netman/ directory creates two executables: netman (GUI frontend) and
backend (CLI backend).
Please ignore the "Sender" parameter not used warnings. It is normal
not to use Sender although there are instances where it is useful.
There are other warnings regarding variables not being initialised.
Sometimes it doesn't make sense to initialise a variable if the
initial value will always be overwritten.
