+====================
+
+NAME
+----
+git-explode-packs - Script used to explode packs in a repository into objects
+
+
+SYNOPSIS
+--------
+'git-explode-packs'
+
+DESCRIPTION
+-----------
+
+This script is used to explode all packs into the constituent objects.
+
+A pack is a collection of objects, individually compressed, with
+delta compression applied, stored in a single file, with an
+associated index file.
+
+Packs are used to reduce the load on mirror systems, backup
+engines, disk storage, etc.
+
+This script removes all the packs in the repository, replacing them with the
+objects that are stored inside them.
