+ * \brief Abstract base class for generators of specific boot image formats.
+ *
+ * Subclasses implement a concrete generator for a certain boot image format, but
+ * they all have the same interface.
+ *
+ * After creating an instance of a subclass the user adds OutputSection objects
+ * to the generator. These objects describe discrete sections within the resulting
+ * boot image file. If the format does not support multiple sections then only
+ * the first will be used.
+ *
+ * Options that are common to all boot image formats are handled by methods
+ * defined in this class. These are the current common options:
+ *	- productVersion
+ *	- componentVersion
+ *	- driveTag
