+ * Menu option types.
+ * There are a number of different layouts for menu options depending
+ * on their types. Currently there are the following possibilities:
+ *
+ * Submenu:
+ * This entry links to a new menu.
+ *
+ * Boolean:
+ * A simple on/off toggle entry. Booleans can be either yes/no, 0/1 or on/off.
+ * Optionally, this entry can enable/disable a set of other options. An example would
+ * be to enable/disable on-board USB, and if enabled give access to further options like
+ * irq settings, base address etc.
+ *
+ * Text:
+ * A single line/limited number of characters text entry box. Text can be restricted
+ * to a certain charset (digits/hex digits/all/custom). Result is also available as an
+ * int if numeric.
+ *
+ * Selection:
+ * One-of-many type of selection entry. User may choose on of a set of strings, which
+ * maps to a specific value for the variable.
+ *
+ * Routine:
+ * Selecting this calls an entry-specific routine. This can be used for saving contents etc.
+ *
+ * Custom:
+ * Display and behaviour of this entry is defined by a set of callbacks.
