+synopsis: "GPT headers that are also valid tar headers"
+description: """
+Marshaling GPT headers such that they are a valid tar archive.
+              The archive will contain a dummy file named `GPTAR` whose content
+              is (at least) the GPT header and the partition table entries.
+              Put a tar-partition at the first available space, and you can
+              inspect the tar archive using regular tar utilities on the disk
+              image with the caveat of the added `GPTAR` dummy file."""
