	This is the top level directory for the nosey package.
	The programs from this package are used to diagnose your
	linux mouse device.

	The README file doubles as both a README and an Bash executable
	package agent -- a program that helps navigate, explain, and
	maintain parts of a software package. { Package Agent (tm) :-) }

	For those who do not have the command shell 'Bash', or have
	trouble using this script, or wish to go straight to using
	the package, here are the manual directions to follow to get
	you going, ASAP.

	1) cd to ..../src
	2) validate or modify makefile defines for your system tools
	3) execute make
	4) execute nosey


	The files located at this level are

	README*		readable bash executable package agent
	briefme*	bash executable package agent

	The subdirectories visible from this level are

	src/		source code to nosey
	bin/		directory for package targets/executables
	doc/		contains things we hope you'll eventually read
	agents/		contains utilities for package agents
	legal/		holds legal sorts of documents
	tmp/		temp dir for manifest checks and misc stuff
	archive/	storage for tar or zipped files

	Note: tmp/ and archive/ are usually not sent with the distribution.
