# if you write separate C files to include in main,
# add their .o targets to the CHILDREN line below
# (e.g. "CHILDREN = myfile.o")
#
# to include code supplied by maevarm, add a .o target
# tag to the parents line (e.g. "PARENTS = "m_bus.o")
# --------------------------------------------------------
MAIN       = main.o m_usb.o
CHILDREN   = 
PARENTS    = 

# --------------------------------------------------------
# if you want to use one of our pre-compiled libraries,
# add it to the line below (e.g. "LIBRARIES = libsaast.a")
# --------------------------------------------------------

# --------------------------------------------------------
# you shouldn't change anything below here,
# unless you really know what you're doing
