This tool makes creating your template structure easy. It does all the pain-in-the-butt work for you, and let's you focus on the template design itself instead of having to build xml files, set up the template structure and so on. This doesn't write the template for you, it just takes out the monotonous and repetitive parts and let's you focus on the design.

Also to install it in NVu, open Nvu, click tools and click extensions. Click install in the window that pops up and browse for the install file (.xpi I think). Then click ok, restart nvu and it will be there.

Apparantly, google is currently having some problems with the company that does it's geocoding, and so the results of what is being showing for lattitude and longtitude is not correct in such tools as google earth (at least for me it wasn't). So I went over to http://www.mapbuilder.net/ and used their services to retrieve long/latt information and 'bingo', I had the exact map I wanted. I struggled for days previously trying to figure out why my maps were showing up incorrectly. Hope this helps someone else.

As for the tool itself, it is very easy to install & use, assuming you have right coordinates =)
