This book started out as bits of documentation written by Subversion project developers, which were then coalesced into a single work and rewritten. As such, it has always been under a free license (see Appendix E, Copyright). In fact, the book was written in the public eye, originally as part of the Subversion project itself. This means two things:
You will always find the latest version of this book in the book's own Subversion repository.
You can make changes to this book and redistribute it however you wish—it's under a free license. Your only obligation is to maintain proper attribution to the original authors. Of course, we'd much rather you send feedback and patches to the Subversion developer community, instead of distributing your private version of this book.
The online home of this book's development and most of the
volunteer-driven translation efforts regarding it is
http://svnbook.red-bean.com. There you can find
links to the latest releases and tagged versions of the book in
various formats, as well as instructions for accessing the
book's Subversion repository (where its DocBook XML source
code lives). Feedback is welcomed—encouraged, even. Please
submit all comments, complaints, and patches against the book
sources to <svnbook-dev@red-bean.com>.
