#
# 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
2011-08-12 22:28:35 +02:00
#
# Limitations:
# - requires UNIX environment
# - TMPDIRNAME must be subdirectory of the current directory.

# Targets
# all build everything
