Project configuration is done in the projdefs.h file. It contains a list of defines that configure the project at compilation. It is very important not to do any project specific configuration in the "src/netcruzer" library files, but only in the projdefs.h file. This will simplify updating to newer versions of the Netcruzer Download in the future. To update to a newer version of the Netcruzer Download, all that should be done is replacing the files contained in the "src/netcruzer" folder with the newer ones.
