- * All attempts to come up with a "common" initialization sequence

- * initialization sequence configurable to the user.
- *
- * The requirements for any new initalization function is simple: it
- * receives a pointer to the "global data" structure as it's only
- * argument, and returns an integer return code, where 0 means
- * "continue" and != 0 means "fatal error, hang the system".
