Description: `
-TODO: Please write this
+The import command imports blocks from an RLP-encoded form. The form can be one file
+with several RLP-encoded blocks, or several files can be used.
+If only one file is used, import error will result in failure. If several files are used,
+processing will proceed even if an individual RLP-file import failure occurs.
