// This tool is a gadget for offline probability training.
// A binary executable aom_entropy_optimizer will be generated in tools/. It
// parses a binary file consisting of counts written in the format of
// FRAME_COUNTS in entropymode.h, and computes the optimized probability table,
// which will be written to a new c file optimized_probs.c according to format
// of entropymode.c file.
//
// Command line: ./aom_entropy_optimizer [directory of the count file]
//
// The input file can either be generated by encoding a single clip by
// turning on entropy_stats experiment, or be collected at a larger scale at
// which a python script which will be provided soon can be used to aggregate
// multiple stats output.
