   9SYNOPSIS
  10--------
  11'git get-tar-commit-id' < <tarfile>

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