+#----------------------------------------------------------------------------\r
+# WinAVR Makefile Template written by Eric B. Weddington, Jörg Wunsch, et al.\r
+#\r
+# Released to the Public Domain\r
+#\r
+# Additional material for this makefile was written by:\r

+# Tim Henigan\r

+# Reiner Patommel\r
+# Markus Pfaff\r
+# Sander Pool\r
+# Frederik Rouleau\r
+# Carlos Lamas\r
+#\r
+# I (Balthasar Szczepanski) 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 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
+# bug reports to the GCC project.\r
