/**
|
|
|
|
Honeycomb data generator.
|
|
|
|
Usage:
|
|
|
|
./hyper -geo 534h -gen-rule honeycomb-rules-534.dat -quit
|
|
./hyper -geo 535h -gen-rule honeycomb-rules-535.dat -quit
|
|
./hyper -geo 435h -gen-rule honeycomb-rules-435.dat -quit
|
|
|
|
You need to change the value of XS7 to 6 (for 435) or 12 (for others)
|
|
|
|
You also need to select 'fp used for rules'
