.SH "DESCRIPTION"
.PP

\fBaccept_check\fR
is a tool to check whether a sentence can be accepted or rejected on a grammar (\fIprefix.dfa\fR
and
\fIprefix.dict\fR). 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
\fBaccept_check\fR.
.PP
This tool needs .dfa, .dict and .term files. You should convert a written grammar file to generate them by
\fBmkdfa.pl\fR.
.PP
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.
.PP
When a word belongs to various category in a grammar,
\fBaccept_check\fR
will check all the possible sentence patterns, and accept it if any of those is acceptable.
