Copyright of the generated source code

The MIT licence allows commercial use of the source and the output of the program. But since I got asked on occasion whether the generated code is encumbered by the copyright of the author, I give my view on this:

The code generated by pycrc is not considered a substantial portion of the software, therefore the licence does not cover the generated code; the author of pycrc will not claim any copyright on the generated code.
