Welcome to Fabric!
Fabric is a high level Python (2.7, 3.4+) library designed to execute shell commands remotely over SSH, yielding useful Python objects in return. It builds on top of Invoke (subprocess command execution and command-line features) and Paramiko (SSH protocol implementation), extending their APIs to complement one another and provide additional functionality.
To find out what's new in this version of Fabric, please see the changelog.
The project maintainer keeps a roadmap on his website.
