AVR-Chat

hi,
 is there any difference in the makefile that is to created for c and c++
files.
as i have file name.cc should i direclty add in make file SRC = name.cc or
name.cpp
i dont how to do it for c++ files.

Regarding my own templates can you give me a  better idea on it so that i
can make it.

Regards

Naveen
