+#  Generic and Simple GNU ARM Makefile 
+#
+#  Desinged for the gnu-arm-none-eabi tool chain
+#
+# 	Features
+#		- create hex file
+#		- create assembler listing (.dis)
+#
+#	Limitations
+#		- only C-files supported
+#		- no automatic dependency checking (call 'make clean' if any .h files are changed)
+#
+#	Targets:
+#		make
+#			create hex file, no upload
+#		make upload
+#			create and upload hex file
+#		make clean
+#			delete all generated files
+#
+#  Note:
+#  	Display list make database: make -p -f/dev/null | less
