     5 1. load OSM data - plain *.osm XML files only at the moment
     6 2. generate vtiles - basically tiled textfiles
     7 3. render from vtiles - only Cairo supported at the moment

     9=== Issues ===
     10==== Vtile generation doesn't scale ====
     11For example, for processing the Czech Republic data (state 16.10.2012) requires about 9.5 GB of RAM. It also just runns in a single thread.
     12
     13There are two possible solutions for the RAM issue:
     14 * iterate more times over the data
     15 * use on disk cache/database for the temporary results
     16  * this is what [http://svn.openstreetmap.org/applications/utils/export/tiledata2/initialParse.py the old OJWs tile data server does] during import
