Remember help lib, sys, and self

Just a reminder... beginning in A109 these three lines are useful. Run R3 and type:

? self

? lib

? sys

Gives you an idea of how the main contexts are set up.

Here's a description:

	self	is your user context, where your main script lives. If you didn't provide a script, it's mostly empty.
	lib	is the export library, and contains all the main functions of the system, as well as any exported module functions.
	sys	is the private system context. What used to be intrinsics now live here. Note that words of value 'done indicate functions that concluded their operation (and are being recycled.)
