Despite spending currently more time using my WaterOnMars
feed reader than developing it, I'm still making small improvements to it. And to make my life easier I could count on a solid little project: fabric
fabric is a Python based command-line utility designed to help running commands remotely: typically to deploy a web app on a remote server.
So I'm using it to deploy WaterOnMars on my personal server and also to deploy the demo version on heroku. But more recently I added fabric's configuration file (the "fabfile") to the sources of the project as an officially maintained helper for development tasks ((well I didn't think of it in such a formal way obviously)). It's now usable to run the test suite, to launch the web app locally, to set-up the db and to deploy it on custom servers.
