   6test_description='git archive and git get-tar-commit-id test
   7
   8This test covers the topics of file contents, commit date handling and
   9commit 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 archive 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 archive 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.
