 .SH DESCRIPTION

 configuration option is enabled. See \fBnotmuch-config\fR(1) for
 details.
 
+Supported options for
+.B tag
+include
+.RS 4
+.TP 4
+.BR \-\-batch
+
+Read batch tagging operations from standard input. This is more
+efficient than repeated
+.B notmuch tag
+invocations. See
+.B TAG FILE FORMAT
+below for the input format. This option is not compatible with
+specifying tagging on the command line.

+.RS 4
+.TP 4
+.BR "\-\-input=" <filename>
+
+Read input from given file, instead of from stdin. Implies
+.BR --batch .
+
+.SH TAG FILE FORMAT
+
+The input must consist of lines of the format:
+
+.RI "T +<" tag ">|\-<" tag "> [...] [\-\-] <" search-terms ">"
+
+Each line is interpreted similarly to
+.B notmuch tag
+command line arguments. The delimiter is one or more spaces ' '. Any
+characters in <tag> and <search-terms>
+.B may
+be hex encoded with %NN where NN is the hexadecimal value of the
+character. Any ' ' and '%' characters in <tag> and <search-terms>
+.B must
+be hex encoded (using %20 and %25, respectively). Any characters that
+are not part of <tag> or <search-terms>
+.B must not
+be hex encoded.
+
+Leading and trailing space ' ' is ignored. Empty lines and lines
+beginning with '#' are ignored.
