DESCRIPTION
accept_check is a tool to check whether a sentence can be accepted or

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.
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.
