Without my children, Julien and Evelyne, this program would never have been created. This program is dedicated to them, in the hope that they will learn the basics of programming by having fun with it. I must also thank Julien for having designed the splash screen as well as the robot image used in the various error dialogs.
I personally have learned much by writing this program - in fact, I had known about Python only for a few months before I embarked on this project and had not programmed for more years than I care to admit. Of course, without the work done by the Python and wxPython community, the learning curve for me would have been much steeper and this program would not have been possible. This program was inspired by Guido van Robot (GvR), a Python-like implementation of Pattis' original Karel the Robot. I have received very useful comments from the GvR team; in particular, I would like to acknowledge the contribution of Stas Zykiewicz, who taught me a great deal about wxPython, and never tired of trying out buggy code I wrote until rur-ple became stable enough to be used by others. Thanks Stas!
Many of the images for buttons have been adapted from the Nuvola icon set, created by David Vignoni. I wish I could create images as esthetically pleasing as Vignoni does.
Tony Payzant spent a fair bit of time proofreading earlier versions of the lessons. Bob Gailer suggested some useful corrections as well.
Luis Sureda provided a Spanish translation and made some useful suggestions to simplify the code related to the language selection.
Richard E. Brown provided some useful bug reports and suggestions so that rur-ple should now work properly under MacOS.
Andy Judkis used rur-ple with his students and made many suggestions for improvement; in many ways, he became a driving force behind this project.
Last but not least, this project wouldn't be what it is today without its availibility in a growing number of languages. A big thank you goes to all the volunteers who found value in RUR-PLE and invested time to provide their local version. We thus would like to thank:
