Viking/Husqvarna Pfaff/Singer 3 VP3

The VP3 file format appears to be series of nested sections. Most sections contain tagged records.

In the style of Backus–Naur Form,

File = File-header Extent

Extent = Extent-header {Hoop}

Hoop = Hoop-header Canvas Threads

Threads = Threads-header {Thread}

Thread = Thread-header Colours Thread-text Thread-detail Stitches Thread-end

Colours = {Colour-detail}

Stitches = Stitches-header {Stitch}

Stitch = Escaped-command | Displacement
