BrightBoard Footnotes
1 For simplicity we refer to the marks as
being `black' on a `white' background. In fact, any coloured pens may be used,
though the thresholding is easier with the darker colours.
2 The final part is more accurately transcribed as: `The
goal "Z is inside Y and Z is not equal to X" cannot be satisfied'
3 The formats `pgm' (portable greymap) and `pbm' (portable
bitmap) are currently supported.
