make 100% compatible with swift.py?

Make Env vars compatible with st?

Get and put the metadata in the libray (x-object-meta-mtime) when getting and putting a file?

This also puts meta-mtime
https://github.com/gholt/swiftly

As an integer, but it does parse it as a float
subargs.append('x-object-meta-mtime:%d' % getmtime(options.input_))

Need an iterate all objects routine... Could use a channel
- could just be a flag to Objects()

FIXME progress meter would be nice! Do this by wrapping the Reader with a progress bar

Do bandwidth limit by wrapping the Reader too

Could have an integrity check mode where we check the MD5sums of the local vs the remote
