Use awk/sed/bash/python/etc to generate a header file to include?

Having some program generate code is probably the easiest way (at
least that I can think of). I mean, in pseudocode, it could just be
like:

for i in states: (I figured NC and CA referred to the states)
for j in number_of_blocks_per_state:
for k in 7:
printf_to_file("const int %sa%dp%dNUM=%d;\n", i, j, k,
read_from_file());

Yeah, it's messy and it's extremely inefficient, but you only need to
do it once (I assume) and it's a lot better than doing it by hand...
