RFacter is a library for collecting facts from remote system(s) by executing commands over transports such as SSH and WinRM.

RuboCop CLI that only lints and auto-fixes code you committed by utilizing `git-log` and `git-diff`. Rfix CLI makes it possible to lint (`rfix lint`) and auto-fix (`rfix local|origin|branch`) code changes since a certain point in history. You can auto-fix code committed since creating the current branch (`rfix origin`) or since pushing to upstream (`rfix local`). Includes a RuboCop formatter with syntax highlighting and build in hyperlinks for offense documentation. Holds the same CLI arguments as RuboCop. Run `rfix --help` for a complete list or `rfix` for supported commands.
