> The S3 Native FileSystem currently writes all files with a set of default headers:
>  * Content-Type: binary/octet-stream
>  * Content-Length: <computed from object size>
>  * Content-MD5: <computed from object data>
> This is a good start, however many applications would benefit from the ability to customize (for example) the Content-Type and Expires headers for the file. Ideally the implementation should be abstract enough to customize all of the available S3 headers and provide a facility for other FileSystems to specify optional file metadata.
