We discuss code changes on the mailing list bup-list@googlegroups.com, but if you'd prefer to begin the process with a pull request, that's just fine. We're happy to have the help. In any case, please make sure each commit includes a Signed-off-by: Someone line in the commit message that matches the "Author" line so that we'll be able to include your work in the project. See ./SIGNED-OFF-BY for the meaning: https://github.com/bup/bup/blob/master/SIGNED-OFF-BY After you submit the pull request, someone will eventually redirect it to the list for review, and you will of course be included in the conversation there. On the other hand, if you're comfortable with "git send-email" (or the equivalent), please post your patches to the list as described in the "Submitting Patches" section in ./HACKING: https://github.com/bup/bup/blob/master/HACKING
