.SS "Argument Parsing:"

    arguments must be separated by white space. eg
        "blender \-ba test.blend"
    ...will ignore the 'a'
        "blender \-b test.blend \-f8"
    ...will ignore 8 because there is no space between the \-f and the frame value
.br
.SS "Argument Order:"

Arguments are executed in the order they are given. eg
        "blender \-\-background test.blend \-\-render\-frame 1 \-\-render\-output /tmp"
    ...will not render to /tmp because '\-\-render\-frame 1' renders before the output path is set
        "blender \-\-background \-\-render\-output /tmp test.blend \-\-render\-frame 1"
    ...will not render to /tmp because loading the blend file overwrites the render output that was set
        "blender \-\-background test.blend \-\-render\-output /tmp \-\-render\-frame 1" works as expected.
