NAME
           accept_check
          - Check whether a grammar accept / reject given word sequences

SYNOPSIS
       accept_check [-t] [-s spname] [-v] {prefix}

DESCRIPTION
       accept_check is a tool to check whether a sentence can be accepted or
       rejected on a grammar (prefix.dfa and prefix.dict). The sentence should
       be given from standard input. You can do a batch check by preparing all
       test sentence at each line of a text file, and give it as standard
       input of accept_check.

       This tool needs .dfa, .dict and .term files. You should convert a
       written grammar file to generate them by mkdfa.pl.

       A sentence should be given as space-separated word sequence. It may be
       required to add head / tail silence word like sil, depending on your
       grammar. And should not contain a short-pause word.

       When a word belongs to various category in a grammar, accept_check will
       check all the possible sentence patterns, and accept it if any of those
       is acceptable.

OPTIONS
        -t
          Use category name as input instead of word.

        -s  spname
          Short-pause word name to be skipped. (default: "sp")

        -v
          Debug output.

EXAMPLES
       An output for "date" grammar:

          % echo '<s> NEXT SUNDAY </s>' | accept_check date
          Reading in dictionary...
          143 words...done
          Reading in DFA grammar...done
          Mapping dict item <-> DFA terminal (category)...done
          Reading in term file (optional)...done
          27 categories, 143 words
          DFA has 35 nodes and 71 arcs
          -----
          wseq: <s> NEXT SUNDAY </s>
          cate: NS_B (NEXT|NEXT) (DAYOFWEEK|DAYOFWEEK|DAY|DAY) NS_E
          accepted
