.SH "NAME"
preview \- Allows the user to \fIpreview\fR animation scripts in MGED\&.
.SH "SYNOPSIS"
.HP \w'\fBpreview\fR\ 'u
\fBpreview\fR [\-v] [\-d\ \fIdelay\fR] [\-D\ \fIstart_frame_number\fR] [K\ \fIend_frame_number\fR] {\fIrt_script_file\fR}
.SH "DESCRIPTION"
.PP
Allows the user to
\fIpreview\fR
animation scripts in MGED\&. The
\fI\-d\fR
option provides a delay in seconds to be applied between each frame (the default is no delay)\&. The
\fI\-D\fR
option allows the user to specify a starting frame number, and the
\fI\-K\fR
option allows the specification of an ending frame number\&. The
\fI\-v\fR
flag indicates that the objects displayed in the MGED graphics window should be displayed in evaluated mode, as would be the result of the
\fBev\fR
command\&. Note that this may significantly slow the
\fIpreview\fR\&.
.SH "EXAMPLES"
.PP
The example shows the use of the
\fBpreview\fR
command to preview specified frames of an animation script\&.
