+ * @title: Content-addressed object store
+ * @short_description: A git-like storage system for operating system binaries
+ *
+ * The #OstreeRepo is like git, a content-addressed object store.
+ * Unlike git, it records uid, gid, and extended attributes.
+ *
+ * There are two possible "modes" for an #OstreeRepo;
+ * %OSTREE_REPO_MODE_BARE is very simple - content files are
+ * represented exactly as they are, and checkouts are just hardlinks.
+ * A %OSTREE_REPO_MODE_ARCHIVE_Z2 repository in contrast stores
+ * content files zlib-compressed.  It is suitable for non-root-owned
+ * repositories that can be served via a static HTTP server.
+ *
+ * To store content in the repo, first start a transaction with
+ * ostree_repo_prepare_transaction().  Then create a
+ * #OstreeMutableTree, and apply functions such as
+ * ostree_repo_stage_directory_to_mtree() to traverse a physical
+ * filesystem and stage content, possibly multiple times.
+ * 
+ * Once the #OstreeMutableTree is complete, stage all of its metadata
+ * with ostree_repo_stage_mtree(), and finally create a commit with
+ * ostree_repo_stage_commit().
