@ -77,6 +77,12 @@ Set the maximum delay between transcript updates to
of seconds. The argument is a floating point number. This can be used to
avoid long pauses in the transcript replay.
.TP
.BR " \-\-summary "
Display details about session recorded in the specified timing file and exit. The session has
to be recorded by "advanced" format (see
.B script (1)
option \fB\-\-logging\-format\fR for more details).
.TP
.BR \-x , " \-\-stream " \fItype\fR
Forces scriptreplay to print only specified stream. The supported stream types
are 'in' or 'out'. This option is recommended for multi-stream logs (e.g. --log-io)
