+.RI typescript
+.SH "DESCRIPTION"
+This program re-run a typescript, using stdin typescript and timing information to ensure that
+input happens in the same rhythm as it originally appeared when the script
+was recorded.
+.PP
+The \fBsession is executed\fR in newly created pseudo terminal with user's $SHELL
+(or defaults to /bin/bash).
+.PP
+.B Be careful!
+Do not forget that the typescript may contains arbitrary commands.
+It is recommended to use \fB"scriptreplay \-\-stream in \-\-log\-in typescript"\fR
+(or with --log-io instead of --log-in) to verify the typescript before it is executed by
+.BR scriptlive (1).
+.PP
+The timing information is what
+.BR script (1)
+outputs to file specified by
+.BR \-\-log\-timing .
+The typescript has to contain stdin information and it is what
+.BR script (1) 
+outputs to file specified by
+.BR \-\-log-in
+or
+.BR \-\-log\-io .
+
+.SH OPTIONS
+.TP
+.BR \-I , " \-\-log-in " \fIfile\fR
+File containing \fBscript\fR's terminal input.
+.TP
+.BR \-B , " \-\-log-io " \fIfile\fR
+File containing \fBscript\fR's terminal output and input.
+.TP
+.BR \-t , " \-\-timing " \fIfile\fR
+File containing \fBscript\fR's timing output.  This option overrides old-style arguments.
+.TP
+.BR \-T , " \-\-log\-timing " \fIfile\fR
+aliast to \fB\-t\fR, maintained for compatibility with
+.B script (1)
+command line options.
+.BR \-d , " \-\-divisor " \fInumber\fR
+Speed up the replay displaying this
+.I number
+of times.  The argument is a floating point number.  It's called divisor
+because it divides the timings by this factor.  This option overrides old-style arguments.
+.TP
+.BR \-m , " \-\-maxdelay " \fInumber\fR
+Set the maximum delay between transcript updates to
+.I number
+of seconds.  The argument is a floating point number.  This can be used to
+avoid long pauses in the transcript replay.
+.TP
+.BR \-V , " \-\-version"
+Display version information and exit.
+.TP
+.BR \-h , " \-\-help"
+Display help text and exit.
