The above statement is not corrent. config file
defines
the flow of packets. The processing is done in each
element. each element is a C++ class and has
set of methods for processing packets.

i think u should know this before ,linux kernel 
modules do not have any single main function.

when a module is loaded init_module is called
and when a module in unloaded cleanup_module is
called.

read the FAQ and the programming manual.

do u have a running machine with click as a kernel 
module?. get one machine up and write a few config
files that will be the start, this u can easily do
after reading edd's thesis. now read the FAQ and look
into each elements source and from there u will know
where to go. Use the programming manual to understand
some aspects of it.
