easymapnik is the beginnings of a project to develop an application to allow easy rendering of OSM data from file or from an OSM data server, without the need to install a PostGIS database, or, ultimately, to write a Mapnik rules file. At the moment it's very much a demo app, rather than a production-ready app, but nonetheless it demonstrates how you can render OSM data from an OSM data source or server. It's available in the "demo" directory and has a Makefile which has so far only been tested on OS X 10.5 with a version of Mapnik dating from early 2009. The usage is:
```
`easymapnik -s source [-w width] [-h height] -x xmlfile [-i InOSMFile] [-o OutPNGFile] [-t] [-z startzoom] [-Z endzoom] [-b bbox] [-u serverURL] [-m]`
