I just updated the includesvg-example. Now it contains everything what was described here. Both the old way and the new way, including the operating system test and my version of the svg-package by Philip Ilten featuring the angle-option to rotate you svg figures. I also added two examples for SVG-figures included from different directories. Everything corrected and tested. Happy TeXing!
Remember that the zip-archive is only named "pdf" to fool wordpress.com and that you have to rename it after download.
