REPO_THINGS is a list of comma-separated words that can include:
    states                           describe the states
    itemsets                         complete the core item sets with their closure
    lookaheads                       explicitly associate lookahead tokens to items
    solved                           describe shift/reduce conflicts solving
    counterexamples, cex             generate conflict counterexamples
    rules                            list unused rules
    terms                            list unused terminals
    verbose                          report detailed internal state and analysis results
    all                              include all the above reports
    none                             disable all reports
