+# WinAVR Makefile Template written by Eric B. Weddington, Jörg Wunsch, et al.\r

+# I (Balthasar Szczepański) made some changes for this project,\r
+# to allow programming with the avt2994 tool and program fuse byte as well.\r
+#\r
+#----------------------------------------------------------------------------\r
+# On command line:\r
+#\r
+# make all = Make software.\r
+#\r
+# make clean = Clean out built project files.\r
+#\r
+# make coff = Convert ELF to AVR COFF.\r
+#\r
+# make extcoff = Convert ELF to AVR Extended COFF.\r
+#\r
+# make program = Download the hex file to the device, using avrdude.\r
+#                Please customize the avrdude settings below first!\r
+#\r
+# make program-fuse = as above but will program the fuse bytes too.\r
+#\r
+# make debug = Start either simulavr or avarice as specified for debugging, \r
+#              with avr-gdb or avr-insight as the front end for debugging.\r
+#\r
+# make filename.s = Just compile filename.c into the assembler code only.\r
+#\r
+# make filename.i = Create a preprocessed source file for use in submitting\r
