"""IGNite: generate the geo-referenced IGN map of an area.

Usage: ignite.py [options] <upper_left> <lower_right> <zoom>

Options:
  -h --help                Show this screen.
  --processes <p>          Number of processes used for requests [default: 4].
  --out <file>             Output filename [default: out].
  --cache-folder <folder>  Cache directory [default: cache].
  --capabilities <file>    Capabilities filename [default: capabilities.xml]
  --no-caching             Do not save temporary tiles for caching and fast reloading.
  --backend <backend>      Which backend to use, between ign and cyclosm [default: cyclosm].
Note:
  Coordinates should be given as latitude,longitude in decimal degrees.
