   22: \ Use this program like this:
   23: \ include it, then the program you want to check; then say print-ans-report

   27: \ Caveats:
   28: 
   29: \ Note that this program just checks which words are used, not whether
   30: \ they are used in an ANS Forth conforming way!
   31: 
   32: \ Some words are defined in several wordsets in the standard. This
   33: \ program reports them for only one of the wordsets, and not
   34: \ necessarily the one you expect.
   35: 
   36: 
   37: \ This program uses Gforth internals and won't be easy to port
   38: \ to other systems.
   39: 
   40: \ !! ignore struct-voc stuff (dummy, [then] etc.).
