+# Arduino 0023 Makefile
+# Uno with DOGS102 Shield
+#
+# written by [email protected]
+# modified by xkonni
+#
+# Features:
+#   - boards.txt is used to derive parameters
+#   - All intermediate files are put into a separate directory (TMPDIRNAME)
+#   - Simple use: Copy Makefile into the same directory of the .pde file
+#
+# Limitations:
+#   - requires UNIX environment
+#   - TMPDIRNAME must be subdirectory of the current directory.
+#
+# Targets
+# 	all		build everything
+#	upload	build and upload to arduino
+#	clean	remove all temporary files (includes final hex file)
+#
+# History
+#	001	28 Apr 2010	first  release
+#	002  05 Oct 2010	added 'uno'
