getdb prototype

This is an experimental database fetching tool for projects using SilverStripe with _ss_environment.php files for database config and Beam. A project's beam.json config is used to find SSH connection details, and the database details for that environment are read from the _ss_environment.php file on the server.

This is essentially a wrapper to build and run a shell command like this:

Authoring commits

We like sensible commit messages. There're a lot of good articles about writing great, useful commit messages, but here's the gist of what we like:

• The single most important thing is: commit messages should explain why you are making the change.
• Think, "what would future me want to know about this change?"
• Avoid committing multiple sets of ideas/changes in the same commit: split them up.
• Don't assume the reader understands what the original problem was.

# I've hard-wired the crappy IR remote that came with a DVB-T RTL-SDR
# dongle into a GPIO pin on the Raspberry Pi. The infrared LED in the
# remote has been removed and replaced with a wire going to GPIO 3.
