+/**
+ * Submodules
+ * ----------
+ *
+ * If you want to iterate the refs of a submodule you first need to add the
+ * submodules object database. You can do this by a code-snippet like
+ * this:
+ *
+ * const char *path = "path/to/submodule"
+ * if (add_submodule_odb(path))
+ * die("Error submodule '%s' not populated.", path);
+ *
+ * `add_submodule_odb()` will return zero on success. If you
+ * do not do this you will get an error for each ref that it does not point
+ * to a valid object.
+ *
+ * Note: As a side-effect of this you cannot safely assume that all
+ * objects you lookup are available in superproject. All submodule objects
+ * will be available the same way as the superprojects objects.
+ *
+ * Example:
+ * --------
+ *
+ * ----
+ * static int handle_remote_ref(const char *refname,
+ * const unsigned char *sha1, int flags, void *cb_data)
+ * {
+ * struct strbuf *output = cb_data;
+ * strbuf_addf(output, "%s\n", refname);
+ * return 0;
+ * }
+ *
