-// CmdSet stores a new image in the graph.
-// Images are stored in the graph using 4 elements:
-//	- A user-defined ID
-//	- A collection of metadata describing the image
-//	- A directory tree stored as a tar archive (also called the "layer")
-//	- A reference to a "parent" ID on top of which the layer should be applied
-//
-// NOTE: even though the parent ID is only useful in relation to the layer and how
-// to apply it (ie you could represent the full directory tree as 'parent_layer + layer',
-// it is treated as a top-level property of the image. This is an artifact of early
-// design and should probably be cleaned up in the future to simplify the design.
-//
-// Syntax: image_set ID
-// Input:
-//	- Layer content must be streamed in tar format on stdin. An empty input is
-//	valid and represents a nil layer.
-//
-//	- Image metadata must be passed in the command environment.
-//		'json': a json-encoded object with all image metadata.
-//			It will be stored as-is, without any encoding/decoding artifacts.
-//			That is a requirement of the current registry client implementation,
-//			because a re-encoded json might invalidate the image checksum at
-//			the next upload, even with functionaly identical content.
