+
+Read a tar archive created by 'git archive' from the standard input
+and extract the commit ID stored in it. It reads only the first
+1024 bytes of input, thus its runtime is not influenced by the size
+of the tar archive very much.
If no commit ID is found, 'git get-tar-commit-id' quietly exists with a
-return code of 1. This can happen if <tarfile> had not been created
+return code of 1. This can happen if the archive had not been created
using 'git archive' or if the first parameter of 'git archive' had been
a tree ID instead of a commit ID or tag.
