Can s3cmd or AWS CLI read object metadata?

Setting metadata via HTTP headers using s3cmd is straightforward enough:

$> s3cmd put --add-header=x-amz-custom-header:true file.txt s3://bucket/

However, it looks like there's no way to read these headers (or some of Amazon's default immutable headers) through s3cmd:

$> s3cmd ls s3://bucket/
2015-03-13 17:51       16   s3://bucket/file.txt

$> s3cmd info s3://bucket/file.txt
s3://bucket/file.txt (object):
File size: 16

Is there no way to read object metadata through the command line?

Maybe I'm misunderstanding what the general uses of object metadata are.

(this is basically a more generic version of this unanswered question: Can s3cmd retrieve metadata of an object on Amazon S3?)
