94 * The reason it's still here is that the rules file format does not
95 * support multiple groups very well, and the rules shipped with
96 * xkeyboard-config (see rules/evdev) depend on this limit extensively.
97 * So just lifting this limit would cause problems for people who will use
98 * more than 4 layouts.
99 * TODO: Fix the group index syntax in the rules format, preferably in a
100 * backwards compatible way.
101 * See e.g. https://bugs.freedesktop.org/show_bug.cgi?id=14372
102 * Note: A limit on the number of groups we *do* depend on is imposed by
103 * the size of the xkb_layout_mask_t type (32). This is more than enough
