+In order to test git-pack-redundant, we will create a number of objects and
+packs in the repository `master.git`. The relationship between packs (P1-P8)
+and objects (T, A-R) is showed in the following chart. Objects of a pack will
+be marked with letter x, while objects of redundant packs will be marked with
+exclamation point, and redundant pack itself will be marked with asterisk.
