I think I'm gonna need some help with this one.

I want to have a detailed map of a few cities pre-cached. I go to the city in question, then

1) Download -> around here -> 20 km
2) down max, up max (by the way, what do "down" and "up" mean? Does "down" mean zoom in, or zoom out?)
3) It works out 23k tiles
4) I zoom around the city and it tells me tiles must be downloaded. I don't know what area was actually downloaded.

I believe I'm wrong somewhere, but don't know where.

It would be of great help actually to have those settings illustrated. Say, here's a modrana window, scale is so and so, and the area to be covered is highlighted in blue for each mode.

By the way, sqlite interactions are prone to segfaults on amd64 python 2.7. It is for sure a regression on Python/SQLite side, but there needs to be a way to work it around.

Also, if anyone has set up a local tile server for modrana to use (say on a local network), could you please share how you did it? The openstreetmap wiki has the notorious open-source documentation problem, where old and outdated docs are intermixed with the current ones in an amusing enough way to leave one occupied for a week if not more.
