93 * by two different parameters:
94 *
95 * - start_committish is the commit-ish, in repository r, that determines
96 * which commits the branches will point to. The superproject branch
97 * will point to the commit of start_committish and the submodule
98 * branches will point to the gitlink commit oids in start_committish's
99 * tree.
100 *
101 * - tracking_name is the name of the ref, in repository r, that will be
102 * used to set up tracking information. This value is propagated to
103 * all submodules, which will evaluate the ref using their own ref
104 * stores. If NULL, this defaults to start_committish.
105 *
106 * When this function is called on the superproject, start_committish
107 * can be any user-provided ref and tracking_name can be NULL (similar
108 * to create_branches()). But when recursing through submodules,
109 * start_committish is the plain gitlink commit oid. Since the oid cannot
110 * be used for tracking information, tracking_name is propagated and
111 * used for tracking instead.
