+test_description='git archive and git get-tar-commit-id test
+
+This test covers the topics of file contents, commit date handling and
+commit id embedding:
+
+ The contents of the repository is compared to the extracted tar
+ archive. The repository contains simple text files, symlinks and a
+ binary file (/bin/sh). Only paths shorter than 99 characters are
+ used.
+
+ git archive applies the commit date to every file in the archive it
+ creates. The test sets the commit date to a specific value and checks
+ if the tar archive contains that value.
+
+ When giving git archive a commit id (in contrast to a tree id) it
+ embeds this commit id into the tar archive as a comment. The test
+ checks the ability of git get-tar-commit-id to figure it out from the
+ tar file.
