Feel free to share with your friends, make printed copies, etc. You can upload this file to your site, as long as you post a link back to this page and/or my blog (where the book was initially posted). You can sell this book only at the cost of the medium! - e.g. the CD you burnt it on, or at the price of toner and paper used for printing.
Customized versions are available for sale on demand, if anyone wants to sell prints commercially. Contact me for pricing and legal info at josef.at.paskvil.dot.com.
