.B \-a, \-\-render-anim 
Render frames from start to end (inclusive)

.TP
.B \-S, \-\-scene <name>
Set the active scene <name> for rendering

.TP
.B \-f, \-\-render-frame <frame>
Render frame <frame> and save it

.TP
.B \-s, \-\-frame-start <frame>
Set start to frame <frame> (use before the \-a argument)

.TP
.B \-e, \-\-frame-end <frame>
Set end to frame <frame> (use before the \-a argument)

.TP
.B \-j, \-\-frame-jump <frames>

.IP
The # characters are replaced by the frame number, and used to define zero padding.
.IP
    ani_##_test.png becomes ani_01_test.png

    eg: blender -b foobar.blend -o //render_ -F PNG -x 1 -a
    //render_ becomes //render_####, writing frames as //render_0001.png//
