     This has been on the wish-list for a long time.  In principle it's
     straight-forward - you redirect mkdata() et al's I/O to another file,
     and modify the skeleton to have a start-up function that slurps these
     into dynamic arrays.  The concerns are (1) the scanner generation code
     is hairy and full of corner cases, so it's easy to get surprised when
     going down this path :-( ; and (2) being careful about buffering so
     that when the tables change you make sure the scanner starts in the
     correct state and reading at the right point in the input file.
     
     > I was wondering if you know of anyone who has used flex in this way.
     
     I don't - but it seems like a reasonable project to undertake (unlike
     numerous other flex tweaks :-).
