$(info Source files can be grouped into subdirectories.)
$(info To build an executable and attempt to upload it,)
$(info use just "make". If the executable requires EEPROM)
$(info initialization, use "make prom".)
$(info )
$(info make mymain.hex --> to build a hex-file for mymain.c)
$(info make mymain.eep --> for an EEPROM file for mymain.c)
$(info make mymain.elf --> for an elf-file for mymain.c)
$(info make ?CFILES --> show C source files to be used)
$(info make ?CPPFILES --> show C++ source files to be used)
$(info make ?HFILES --> show header files found)
$(info make ?HPATHS --> show header locations)
$(info make ?CFLAGS --> show compiler options)
