19 :     * 2. newly required privileges
20 : blume 330 * 3. privileges that would be granted once the group is stabilized
21 :     *
22 : blume 340 * The list of sub-libraries includes an AbsPath.t. This is the path
23 : blume 330 * that was originally found in the CM description file and led to
24 : blume 340 * inclusion of the sublibrary. This contrasts
25 :     * with the "grouppath" member of the sublibrary itself which
26 : blume 330 * records the path of its actual description file.
27 :     * The two paths are not necessarily equal because of aliases. *)
