Convenient Filesystem interface over S3

 Pythonic file interface to S3, s3fs builds on top of botocore.
 .
 The top-level class S3FileSystem holds connection information and
 allows typical file-system style operations like cp, mv, ls, du,
 glob, etc., as well as put/get of local files to/from S3.
 .
 The connection can be anonymous - in which case only
 publicly-available, read-only buckets are accessible - or via
 credentials explicitly supplied or in configuration files.
 .
 Calling open() on a S3FileSystem (typically using a context manager)
 provides an S3File for read or write access to a particular key.
 The object emulates the standard File protocol (read, write, tell,
 seek), such that functions expecting a file can access S3.
 Only binary read and write modes are implemented, with blocked
 caching.
 .
 S3Fs uses and is based upon fsspec.
