OSM Tile Server with Custom Projection Systems

I am trying to install the OSM tile server on a local machine with a custom projection system like epsg:3573. For the server installation I followed this tutorial (http://switch2osm.org/serving-tiles/building-a-tile-server-from-packages/) and it works fine with the default settings. For making changes, I played around with osm.xml and changed the srs information in there but still no luck. It would be appreciated if anyone can give me some hints on customizing the OSM tile server with a custom projection system.

Thanks,
Ebrahim
