It says the small tables in src/sam_abbrev_tab.h, src/sam_pos_rules.h, and src/sam_words_tab.h were transcribed from the engine.",
    "The README says about 99.7% of samples match exactly and the rest differ by float rounding, and reports 21/21 corpus sentences, 104/104 number and date lines, 100/100 homograph sentences, and 180/180 paragraphs of Alice in Wonderland. tools/compare_corpus.py compares the C output with WAVs that the README says are not included.",
