Hi, one (Java) source file of an ITP package (jcdf) has the following comments:
* The code for the Huffman and Adaptive Huffman decompressing stream * implementations in this class is based on the C implementation in * "The Data Compression Book" (Mark Nelson, 1992), via the code * in cdfhuff.c from the CDF source distribution. * * <p>On the topic of intellectual property, Mark Nelson * <a href="http://marknelson.us/code-use-policy">says</a>: * <ul> * <li>It is my intention that anyone who buys the book or magazine be free * to use the source code in any form they please. I only request that * any use that involves public reproduction include proper attribution. * any use that involves public reproduction include proper attribution. * <li>I assert that in no case will I initiate or cooperate with any attempt * to enforce the copyright on the source code, whether it belongs to me * or a publisher. * </ul> * And I even bought the book (MBT). https://anonscm.debian.org/cgit/debian-astro/packages/jcdf.git/tree/BitExpandInputStream.java What is this? No-enforce-copyright with an attribution requirement? Upstream itself uses LGPL-3. Best regards Ole
