I noticed that in the COPYING file, it is indicated that the files are licensed under the BSD or D&R license. However, the text below the title "BSD License" is that of the Expat (former MIT) license. Given that most of the projects of why the luck stiff were licensed under this MIT/Expat license, should we consider that the license to use is Expat instead of BSD?
