</div>That sums it upp pretty nicely. I just made it look ugly, to increase the pressure on you to submit patches :-))<br>

</div>I don't think the "old" stitcher did that, did it? I thought we were all still waiting for someone to sort out the projection issues in osma, so that captions were actually were the corresponding cities were :-).<br>

</div>Allan, much appreciated. I would like to remove as much hardcoded things as I can (if performance of tile serving doesn't suffer too much). If there are other dependencies we should add them to the INSTALLATION instructions. You do have an SVN account, so feel free to change the INSTALL doc, or add other documentation files.<br>

</div>The usage of Cairo is pretty primitive (exclusively used for stitching), we could easily switch to PIL (python imaging library), although I guess that that wouldn't really help you :-). Any other language could also be used, although python is easiest as it has access to the PNG data of tiles without needed to use a command line client. Although it would be kind of trivial to write a tile extractor in perl too.<br>
