Functions
	printf ("static const uint8_t my_array[100] = {\n")
	write_uint8_t_array (my_array, 100)
	printf ("};\n")
	WRITE_ARRAY ("static const", uint8_t, my_array)
	write_fileheader () adds some minor things like a "this is a generated file" comment and some standard includes. tablegen.h defines some write functions for one- and two-dimensional arrays for standard types - they print only the "core" parts so they are easier to reuse for multi-dimensional arrays so the outermost
