[MapProxy] mapproxy-seed - Create OSM like tile structure

[Debasish Sahu]

Many thanks again.

Here's how I have declared the grid

grids:
  mygrid:
    srs: 'EPSG:900913'
    bbox: [-20037508.34, -20037508.34, 20037508.34, 20037508.34]
    bbox_srs: EPSG:900913

Should I keep the Google Extents or the extents of my data (8596550.829,
3340667.637, 8598788.35, 3342816.079) in the grid definition ?

Pls. advise
