Before I do that, I would like to learn a litte more about the legal aspects of open-source software. What would be a good introductory reading? Plus, I have one very specific question: In my package, I use modified code from sre_parse.py, which is part of the Python release. That file has the following header: # # Secret Labs' Regular Expression Engine # # convert re-style regular expression to sre pattern # # Copyright (c) 1998-2001 by Secret Labs AB. All rights reserved. # # See the sre.py file for information on usage and redistribution. # The referenced information is missing in the version of sre.py that comes with current versions of Python, but I found it in the archive http://effbot.org/media/downloads/sre-2.2.1.zip. It reads: # # Secret Labs' Regular Expression Engine # # re-compatible interface for the sre matching engine # # Copyright (c) 1998-2001 by Secret Labs AB. All rights reserved. # # This version of the SRE library can be redistributed under CNRI's # Python 1.6 license. For any other use, please contact Secret Labs # AB (info@pythonware.com). # # Portions of this engine have been developed in cooperation with # CNRI. Hewlett-Packard provided funding for 1.6 integration and # other compatibility work. # Now, how am I supposed to deal with that? Ask Secret Labs for some kind of permission? Leave it as it is and add my own copyright line? Malte
