# This script converts input binary blob into output .h file,

# The three command line arguments are:
#
# - name of the variable to define in the output .h file
# - input binary blob to be converted to hex ASCII
# - name of the output file
#
# The output file contains a C #define statement assigning the variable to hex
# dump of the input file.

# This script is supposed to be invoked from the make file, no command line
# argument verification is done.
# Make sure the user is alerted if not enough command line arguments are
# supplied.
