Makefile target examples:
make all - Compile driver and utilities against current running kernel
make all USER_OPT=-DDEBUG - Compile with debugging code and messages

make install - Copy driver and utilities into standard locations (needs root)
make install PREFIX=/usr - Copy utilities to /usr/bin instead of /usr/local/bin
make install MODULE_DIR=/lib/modules/2.4.0 - Copy module to /lib/modules/2.4.0/misc
make clean - Remove object files from the source directory

Current configuration:
