COMMENT_TEMPLATE ="""Hello stranger, thanks for your contribution to GNOME.

Unfortunately the GNOME repositories in the GitHub mirror do not accept pull requests.

The GNOME project requires contributions to be sent as rebased patches to Bugzilla, although some maintainers are happy to do the rebase work themselves from a GitHub pull request branch.

GNOME is a large project with a long commit history, spanning many years, and unfortunately the GitHub merge workflow creates an obfuscated commit log that makes the life of the maintainers really hard in the long run.

Please do not take this as a rejection of your contribution, GNOME needs and relies on the support of volunteers all over the world, and we need people like you.

We would really appreciate it if you could create a GNOME bugzilla account in case you don't have one already and file a bug there with either an attachment or at least a link to your branch in github:
%s

Again, thanks again for the time you're commiting to improve GNOME.
Happy hacking!
