If you are interested in contributing to CGDB, discuss your ideas with CGDB's active maintainers. Once a feature or bug has been agreed to be worked on by both parties, fork CGDB and develop your feature in a new branch. Commit and push your changes and send a pull request when ready.
CGDB uses the signed-off-by language and process, used by the Linux kernel, to give us a clear chain of trust for every patch received.
In short, you need to include a signed-off-by tag in every patch. This is a developer's certification that he or she has the right to submit the patch for inclusion in this project. It is an agreement to the Developer's Certificate of Origin (below). Code without a proper signoff cannot be merged into the mainline.
When submitting code for inclusion in CGDB, you agree to allow the project owners to license your work under the terms of the Modified BSD License and the GPL version 2 or later.
To sign-off a commit, use the -s or --signoff option.
