+Overview
+--------
+
+Extend the upstream golang stdlib `archive/tar` library, to expose the raw
+bytes of the TAR, rather than just the marshalled headers and file stream.
+
+The goal being that by preserving the raw bytes of each header, padding bytes,
+and the raw file payload, one could reassemble the original archive.
+
+
+Caveat
+======
+
+Eventually this should detect TARs that this is not possible with.
+
+For example stored sparse files that have "holes" in them, will be read as a
+contiguous file, though the archive contents may be recorded in sparse format.
+Therefore when adding the file payload to a reassembled tar, to achieve
+identical output, the file payload would need be precisely re-sparsified. This
+is not something I seek to fix imediately, but would rather have an alert that
+precise reassembly is not possible.
+
+
+Contract
+========

+Do not break the API of stdlib `archive/tar`
