Please do, thank you.

I don't know that it is but wikipedia seems to think that the "ustar  "
indicates it's GNU Tar format.

I couldn't find it in GNU Tar's Texinfo doc (it does have some
description of tar-format, as well as discussions about various formats
w.r.t how well each one is supported and how to choose among them).

Hopefully the source code has further info (well it surely does have,
in the form of actual code ;-),
