+This project is a wrapper around the S3 file system from the Presto
project which shades all dependencies.
+Initial simple tests seem to indicate that it responds slightly faster
+and in a bit more lightweight manner to write/read/list requests, compared
+to the Hadoop s3a FS, but it has some semantic differences.
+
+We also relocate the shaded Hadoop version to allow running in a different
+setup. For this to work, however, we needed to adapt Hadoop's
`Configuration`
+class to load a (shaded) `core-default-shaded.xml` configuration with the
+relocated class names of classes loaded via reflection
+(in the fute, we may need to extend this to `mapred-default.xml` and
`hdfs-defaults.xml` and their respective configuration classes).
