Copyright of the generated source code

Prior to v0.6, pycrc was released under the GPL and an additional addition to the licence was required to permit to use the generated source code in products with a OSI unapproved licence. As of version 0.6, pycrc is released under the terms of the MIT licence and such an additional clause to the licence is no more required. The code generated by pycrc is not considered a substantial portion of the software, therefore the licence does not cover the generated code, and the author of pycrc will not claim any copyright on the generated code.
