        --replay-bin=$CHROME_SRC/third_party/webpagereplay/replay.py \
        --replay-wpr=$INPUT_DIR/top25.wpr \

  5. Move results file to a subdirectory: mkdir $VERSION_DIR; mv *.txt $VERSION_DIR
  6. Repeat from step 1 with a different configuration (e.g. --js-flags="--nolazy").
  7. Create the final results file: ./callstats.py json $VERSION_DIR1 $VERSION_DIR2 > result.json
