The olex package contains this license for text files: LICENSE.TEXT
This file describes the license on any text file in this distribution, hereafter called the TEXT. This license does specifically not apply to any file in this distribution which might end in .h or .cc, nor does it apply to the LICENSE file which is a copy of the GPL and carries a copyright and copying clause on its own. You are free to make hard copies of this file but you may not charge any money for the hard copy. You are free to copy and distribute any file of the TEXT. You are free to copy and distribute a part of any file of the TEXT if you clearly mark its origins. You are free to quote any TEXT file no more than three consecutive paragraphs. You are free to change any file of the text and distribute the result if you clearly mark the changes. The original text, a patch file and a makefile to automatically patch the text is an acceptable combination. You may claim copyright on the patch file only. You may claim any fair use clause given by the law of your country. Whatever way you choose to redistribute anything of the TEXT files, you should do so under this license, except for the fair use clause and for the patch file mentioned a few paragraphs earlier. If anything in this license contradicts your local law, this license is totally null and void and you should delete any of the TEXT files. Any TEXT file is copyrighted by Bart Vanhauwaert, 1998. I think the second paragraph makes it non-DFSG-free. Richard Braakman
