   9SYNOPSIS
  10--------
  11[verse]
  12'git get-tar-commit-id' < <tarfile>
  13
  14
  15DESCRIPTION
  16-----------
  17Acts as a filter, extracting the commit ID stored in archives created by
  18'git archive'.  It reads only the first 1024 bytes of input, thus its
  19runtime is not influenced by the size of <tarfile> very much.
  20
  21If no commit ID is found, 'git get-tar-commit-id' quietly exists with a
  22return code of 1.  This can happen if <tarfile> had not been created
  23using 'git archive' or if the first parameter of 'git archive' had been
  24a tree ID instead of a commit ID or tag.
