+ * \file puzzle bus driver implementation
+ *
+ * Most \c pbdrv_* functions have a weak implementation, which may be
+ * overwritten by a custom implementation. This allows you to use the default
+ * implementation where possible, and only implement extensions required for
+ * your puzzle module. Please see spec.adoc for more information about how to
+ * use the puzzle bus driver library.
