moved some stuff to Tools; added some descriptions

Demo/README

 This directory contains various demonstrations of what you can do with
-Python.  Most demos are grouped sub(sub*)directories according to
-required optional built-in modules or specific platform; there is also
-a set of generally useful scripts and there are some more-or-less
-complete applications.
+Python.  They were all written by me except where explicitly stated
+otherwise -- in general, demos contributed by others ends up in the
+../Contrib directory, unless I think they're of utmost general
+importance (like Matt Conway's Tk demos).
+
+A fair number of utilities that are useful when while developing
+Python code can be found in the ../Tools directory -- some of these
+can also be considered good examples of how to write Python code.
+
+Finally, in order to save disk space and net bandwidth, not all
+subdirectories listed here are distributed.  They are listed just
+in case I change my mind about them.
