For any system designed here, some sort of debug and
syslog is included at the design stage. To start, always
an led or two hanging off spare port lines, then a simple
class / value pair syslog facility, with an output to
leds or a uart.

A simple syslog can be implemented in less than a page of
code, with an array of structures for the subsystem class
and value pairs. Everything in the system that can have
an error condition or other useful info has an entry.

Trivial stuff really, but gets the job done...
