While I prefer that people use the HTML version hosted at http://book.xogeny.com, I don't want to restrict the book to purely online uses (hence the CC license to allow redistribution as is).
I welcome pull requests. Pull requests make it very easy for me to incorporate changes and greatly improve the chances that your contribution will be accepted. But, if you submit a pull request I'll need you to sign a contributor agreement that signs the copyright over to me. This is not an attempt to take credit for work done by contributors, it is merely a way to avoid any legal complications. If you make such contributions I will gladly acknowledge them in the book.
The source code of the ModelicaByExample library is released under an
MIT license. Reader are encouraged to use the examples as starting points
for their own experimenting and should feel free to do so without legal concerns.
People should feel free to fork the distribution for the purpose of making pull requests. But a license is NOT granted for redistribution of the source code or derived works. If you'd like to improve the book, please submit a pull request and I will gladly incorporate your changes into the next release of the book. What I don't want is lots of slightly different versions of the book floating around. These restrictions are meant to make sure contributions are consolidated back into the book.
Feel free to contact me if you have questions or if you have a need for alternative licenses.
