+If the first few bytes of a file indicate that the file contains binary
+data, assume that the file is of type @var{type}.  By default,
+@var{type} is @samp{binary}, and @command{grep} normally outputs either
+a one-line message saying that a binary file matches, or no message if
+there is no match.  If @var{type} is @samp{without-match},
+@command{grep} assumes that a binary file does not match.  If @var{type}
+is @samp{text}, @command{grep} processes a binary file as if it were
+text; this is equivalent to the @samp{-a} or @samp{--text} option.
+@emph{Warning:} @samp{--binary-files=text} might output binary garbage,
+which can have nasty side effects if the output is a terminal and if the
+terminal driver interprets some of it as commands.
