 Etiquette is a tag-based file organization system with a web front-end.

 - Run `python etiquette_flask_launch.py [port]` to launch the flask server. Port defaults to 5000 if not provided.
 - Run `python -i etiquette_repl_launch.py` to launch the Python interpreter with the PhotoDB pre-loaded into a variable called `P`. Try things like `P.new_photo` or `P.digest_directory`.
 - Note: Do not `cd` into the frontends folder. Stay wherever you want the photodb to be created, and start the frontend by specifying full file path of the launch file.

 1. Use the PYTHONPATH technique to make `etiquette` and `etiquette_flask` both importable. Symlinking into the lib is not as convenient here because the server relies on the static files and jinja templates relative to the code's location.

 ### Project stability
 
 You may notice that Etiquette doesn't have a version number anywhere. That's because I don't think it's ready for one. I am using this project to learn and practice, and breaking changes are very common.
