   6 test_description='git tar-tree and git get-tar-commit-id test
   7
   8 This test covers the topics of file contents, commit date handling and
   9 commit id embedding:
  10
  11   The contents of the repository is compared to the extracted tar
  12   archive.  The repository contains simple text files, symlinks and a
  13   binary file (/bin/sh).  Only paths shorter than 99 characters are
  14   used.
  15
  16   git tar-tree applies the commit date to every file in the archive it
  17   creates.  The test sets the commit date to a specific value and checks
  18   if the tar archive contains that value.
  19
  20   When giving git tar-tree a commit id (in contrast to a tree id) it
  21   embeds this commit id into the tar archive as a comment.  The test
  22   checks the ability of git get-tar-commit-id to figure it out from the
  23   tar file.
