convert - Finding good Mbtiles to png tiles converter?

I'm trying to create a slippy map and I need to obtain png tiles. I have exported a .mbtiles file from TileMill and I tried several python scripts to convert this file into png tiles but I always end up with a messy folder where the tiles are misnamed, and I can't use them into my app.

Does anyone know a good converter which organize and name your tiles properly?

Answer

Try mbutil by authors of MBTiles format. Usage is explained on that page.
