a821 [1] filed a deletion request for titan-bot-git [2]: Out of date for more that two years due to deprecated git protocol. Upstream archived last year. The last commit (5 years ago) updated the README file to indicate that the project is unmaintained. Finally, it doesn't build even after fixing the git sources.
