"""
fs: a filesystem abstraction.
This module provides an abstract base class 'FS' that defines a consistent
interface to different kinds of filesystem, along with a range of concrete
implementations of this interface such as:
OSFS: access the local filesystem, through the 'os' module
TempFS: a temporary filesystem that's automatically cleared on exit
MemoryFS: a filesystem that exists only in memory
ZipFS: access a zipfile like a filesystem
SFTPFS: access files on a SFTP server
S3FS: access files stored in Amazon S3
