Need help/doc owning PECL module

Greetings, I am now team lead for the ibm_db2 module on pecl and have been given karma to the repos. I am brand new to PECL ownership and this ecosystem in general, so thanks in advance for your patience for what's going to be a very novice request. I would like to perform the following tasks: - Merge code from a PR (maybe 2 or 3) on GitHub - Publish a new release to PECL with those code changes However, in my quest to figure this out, I've gotten more questions than answers. For instance: - How does one get write authority to the GitHub repos? - Why does the summary page at http://git.php.net/?p=pecl/database/ibm_db2.git have three URLs for the git repo? - I can clone the git.php.net repo, but how/when is this bridged to/from GitHub? Are there tools for dealing with PRs? Do I need to manually merge the PRs from GitHub and then push them into the php.net repo? - Is the GitHub repo an automatically-updated mirror? In a nutshell, I'm looking for any answers to the above questions and some simple guidance on what the "proper" steps are for merging in these PRs and pushing out an update. I suspect there's documentation somewhere that explains all of this, but I'm having trouble finding it. Any guidance or RTFM (with links) is appreciated. Thanks!
