+If you are curious about the actually size of the automata produced by
+=ltl2ba=, =ltl3ba=, and =ltl2tgba -s= in the above example, you can
+quickly build a CSV file using the following pipeline where each
+command append a new column.  We wrap =ltl2ba= and =ltl3ba= with
+=ltldo= so that they can process one column of the CSV that is input,
+and output statistics in CSV as output.  =ltl2tgba= does not need
+that, as it already supports those features. In the resulting CSV
+file, displayed as a table below, entries like =2s 4e 0d= represent an
+automaton with 2 states, 4 edges, and that is not deterministic.  .
+(We have a [[file:csv.org][separate page]] with more examples of reading and writing CSV
+files.)
