code style:

large machines:
   --integral-tables    Use integers for table data (default)
   --string-tables      Encode table data into strings for faster host lang
                        compilation
analysis:
   --prior-interaction          Search for condition-based general repetitions
                                that will not function properly due to state mod
                                overlap and must be NFA reps.
   --conds-depth=D              Search for high-cost conditions inside a prefix
                                of the machine (depth D from start state).
   --state-limit=L              Report fail if number of states exceeds this
                                during compilation.
   --breadth-check=E1,E2,..     Report breadth cost of named entry points and
                                the start state.
   --input-histogram=FN         Input char histogram for breadth check. If
                                unspecified a flat histogram is used.
testing:
   --kelbt-frontend        Compile using original ragel + kelbt frontend
                           Requires ragel be built with ragel + kelbt support
   --colm-frontend         Compile using a colm-based recursive descent
                           frontend
   --reduce-frontend       Compile using a colm-based reducer (default)
   --var-backend           Use the variable-based backend even if the host lang
                           supports goto-based
   --supported-host-langs  Show supported host languages by command line arg
   --supported-frontends   Show supported frontends
   --supported-backends    Show supported backends
   --force-libragel        Cause mainline to behave like libragel
