About
The logo is based on and uses at some parts a font called "Paneuropa Road" by Peter Wiegel which was released under "Open Font License".
You can download the font e.g. here: http://www.fontspace.com/peter-wiegel/paneuropa-
The ® symbol was created using "Liberation Sans" font at size 24pt and is converted to paths/curves so it is not necessary to have it installed at all.
The latest versions of the logo were edited and saved as Inkscape SVG file using Inkscape on Linux.
