XCSoar mapgen usage example

As of 2017-10-06: If the XCSoar Map Generator site does not work or you want to use the Map Generator in your own project, you can do so as described here. You don't need to know any programming language if you only want to generate maps for XCSoar.

Windows

Disclaimer: I'm writing this up based on my assumptions, have not tried Windows, so YMMV. (!) Read the comment first!

All the required tools and dependencies are available on Windows
