+eval-accounting-overhead -- evaluate overhead of various accounting methods and energy/power/timestamp integer sizes
+
+Usage:
+PYTHONPATH=lib bin/eval-accounting-overhead.py <files ...>
+
+Data Generation:
+for accounting in static_state_immediate 'static_state' 'static_statetransition_immediate' 'static_statetransition'; do for intsize in uint16_t uint32_t uint64_t; do PYTHONPATH=~/var/ess/aemr/dfatool/lib ~/var/ess/aemr/dfatool/bin/generate-dfa-benchmark.py --timer-pin=GPIO::p1_0 --sleep=30 --repeat=10 --depth=10 --arch=msp430fr5994lp --app=test_benchmark --trace-filter='setup,setAutoAck,write,getEnergy,$' --timing --dummy= --accounting=${accounting},ts_type=${intsize},power_type=${intsize},energy_type=${intsize} model/driver/nrf24l01.dfa ~/var/projects/multipass/src/app/test_benchmark/main.cc; done; done

+Feed the resulting files into this script, output is one line per file
