- * The xkb_keycodes section
- * ========================
- *
- * This is the simplest section type, and is the first one to be
- * compiled. The purpose of this is mostly to map between the
- * hardware/evdev scancodes and xkb keycodes. Each key is given a name
- * of up to 4 letters, by which it can be referred to later, e.g. in the
- * symbols section.
- *
- * Minimum/Maximum keycode
- * -----------------------
- * Statements of the form:
- * minimum = 8;
- * maximum = 255;
- *
- * The file may explicitly declare the minimum and/or maximum keycode
- * contained therein (traditionally 8-255, inherited from old xfree86
- * keycodes). If these are stated explicitly, they are enforced. If
- * they are not stated, they are computed automatically.
- *
- * Keycode statements
- * ------------------
- * Statements of the form:
- * <TLDE> = 49;
- * <AE01> = 10;
- *
- * The above would let 49 and 10 be valid keycodes in the keymap, and
- * assign them the names TLDE and AE01 respectively. The format <WXYZ> is
- * always used to refer to a key by name.
- *
- * [ The naming convention <AE01> just denoted the position of the key
- * in the main alphanumric section of the keyboard, with the top left key
- * (usually "~") acting as origin. <AE01> is the key in the first row
- * second column (which is usually "1"). ]
- *
- * In the common case this just maps to the evdev scancodes from
- * /usr/include/linux/input.h, e.g. the following definitions:
- * #define KEY_GRAVE 41
- * #define KEY_1 2
- * Similar definitions appear in the xf86-input-keyboard driver. Note
- * that in all current keymaps there's a constant offset of 8 (for
- * historical reasons).
- *
- * If there's a conflict, like the same name given to different keycodes,
- * or same keycode given different names, it is resolved according to the
- * merge mode which applies to the definitions.
- *
- * The reason for the 4 characters limit is that the name is sometimes
- * converted to an unsigned long (in a direct mapping), instead of a char
- * array (see KeyNameToLong, LongToKeyName).
- *
- * Alias statements
- * ----------------
- * Statements of the form:
- * alias <MENU> = <COMP>;
- *
- * Allows to refer to a previously defined key (here <COMP>) by another
- * name (here <MENU>). Conflicts are handled similarly.
- *
- * Indicator name statements
- * -------------------------
- * Statements of the form:
- * indicator 1 = "Caps Lock";
- * indicator 2 = "Num Lock";
- * indicator 3 = "Scroll Lock";
- *
- * Assigns a name the indicator (i.e. keyboard LED) with the given index.
- * The amount of possible indicators is predetermined (XKB_NUM_INDICATORS).
- * The indicator may be referred by this name later in the compat section
- * and by the user.
- *
- * Effect on the keymap
- * --------------------
- * After all of the xkb_keycodes sections have been compiled, the
- * following members of struct xkb_keymap are finalized:
- * xkb_keycode_t min_key_code;
- * xkb_keycode_t max_key_code;
- * darray(struct xkb_key_alias) key_aliases;
- * char *keycodes_section_name;
- * The 'name' field of indicators declared in xkb_keycodes:
- * struct xkb_indicator_map indicators[XKB_NUM_INDICATORS];
- * Further, the array of keys:
- * darray(struct xkb_key) keys;
- * had been resized to its final size (i.e. all of the xkb_key objects are
- * referable by their keycode). However the objects themselves do not
- * contain any useful information besides the key name at this point.
