Afero - A FileSystem Abstraction System for Go

Afero is an filesystem framework providing a simple, uniform and universal API interacting with any filesystem, as an abstraction layer providing interfaces, types and methods. Afero has an exceptionally clean interface and simple design without needless constructors or initialization methods.Afero is also a library providing a base set of interoperable backend filesystems that make it easy to work with afero while retaining all the power and benefit of the os and ioutil packages.

Afero provides significant improvements over using the os package alone, most notably the ability to create mock and testing filesystems without relying on the disk.
