usage() {
cat << EOF
Usage: $0 [Options] --input filename.pcb
  -h, --help                      Print this help message

  -v, --verbose                   Verbose operation

  --input filename.pcb            File to read PCB data from

  File generation:
  --prefix prefix                 prefix (defaults to basename of filename)
  --output-format (eps|gbr)       Generate EPS or Gerber output (default: eps)
  --use-dos-filenames             Use DOS 8.3 filenames

  Image transformation:
  --scale scaling-factor          Factor to resize an image (default: 1.0)
  --mirror                        Produce a mirrored/reversed image
  --rotate
  --color
  --invert
  --outline

  Add extra data to images:
  --add-alignment
  --add-drill-helper

Example:
  $0 --mirror --prefix output_mirrored --input mypcbfile.pcb
