BNFC currently is licensed under GPL-2 which is a bit strict and excludes e.g. industrial users from using the sample grammars (and even the bnfc tool) in closed-source projects.

The following list serves to organize the process and can be extended with new information.

TODO:

  • Discuss on mailing list.
  • Decide on a new license: BSD-3-clause.
  • Draft letter to developers with instructions how to give written consent (public key / signed sheet of paper?)
  • Set response date for reply and email to developers.
    * Decide whom to send this email (even 1-patch contributors? --- some did not even leave their real name).
    * For git developers, https://github.com/BNFC/bnfc/blob/master/.mailmap might help.
    * Collect emails of older developers.
  • Await responses and add them to the repository (for future reference).
  • Change global license setting in github.
  • Remove GPL-2 text from all files. (Consider whether to swap in the new text instead---I'd rather not.)
  • Fix some policies for authorship/copyright notices in files (currently, some files have the original authors, newer authors are hardly represented).

Also add command-line options --help and --license.
The latter prints the license text, which is verbatim the content of
the LICENSE file.
