+       Instead of writing the results out to `$GIT_INDEX_FILE`,
+       write the resulting index in the named file.  While the
+       command is operating, the original index file is locked
+       with the same mechanism as usual.  The file must allow
+       to be rename(2)ed into from a temporary file that is
+       created next to the usual index file; typically this
+       means it needs to be on the same filesystem as the index
+       file itself, and you need write permission to the
+       directories the index file and index output file are
+       located in.

        The id of the tree object(s) to be read/merged.
