file 1:5.38-5 formats explained:
$ file doomseeker-{v7,ustar,pax,gnutar}.tar
doomseeker-v7.tar:     tar archive
doomseeker-ustar.tar:  POSIX tar archive
doomseeker-pax.tar:    POSIX tar archive
doomseeker-gnu.tar:    POSIX tar archive (GNU)

These tarballs were created like so (/home/wub/.local/src/doomseeker/doomseeker being the Git repository's master branch HEAD, with no build/ directory):
$ pwd
/home/wub/.local/src/doomseeker
$ tar --version
