[MapProxy] mapproxy-seed - Create OSM like tile

[Mayeul Kauffmann]

Hello,

I'm trying to do something similar to Debasish Sahu: transforming maps
from my WMS into tiles visible with openlayers from a plain file system,
using mapproxy.
(Context is this:  http://wiki.openstreetmap.org/wiki/ViaAlpina  )
Currently I'm "seeding" simply by browsing the demo (which I updated for
my WMS URL):
http://localhost:8080/demo/?tms_layer=osm&format=png&srs=EPSG%3A900913

Vertical tile order is incorrect.
Following your suggestions, I tried playing around with y
For instance var y = 2^z - 1 - Math.round ((this.maxExtent.top -
bounds.top) / (res * this.tileSize.h));
but it did not work.
I've tried the dame approach modifying the various examples I found
there,
http://openlayers.org/dev/examples/tms.html
http://wiki.openstreetmap.org/wiki/OpenLayers_Simple_Example

without any success.
Do you have any simple openlayers page that correctly get the /y/ from a
a tms cache?
My mapproxy.yaml is this:

    # srs: ['EPSG:4326', 'EPSG:900913']
