Makefile

#
# 'make depend' 		uses makedepend to automatically generate dependencies 
#               		(dependencies are added to end of Makefile)
# 'make' or 'make all'	build executable file 'randqd_example' and 'randq_utest'
# 'make randq_example'		build executable file 'randq_example'
# 'make randq_utest'	build executable file 'randq_utest'
# 'make clean'  		removes all .o 
# 'make clean_all'  	removes all .o and executable files
