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 re-
     jected 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  ac-
     cept_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  re-
     quired 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.

      -s  spname

      -v

	% 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
