  15DESCRIPTION
  16-----------
  17
  18Read a tar archive created by 'git archive' from the standard input
  19and extract the commit ID stored in it.  It reads only the first
  201024 bytes of input, thus its runtime is not influenced by the size
  21of the tar archive very much.
  22
  23If no commit ID is found, 'git get-tar-commit-id' quietly exists with a
  24return code of 1.  This can happen if the archive had not been created
  25using 'git archive' or if the first parameter of 'git archive' had been
  26a tree ID instead of a commit ID or tag.
