Initial import of fs-kit-0.4 into the Packages Collection.

	Welcome to the File System Construction Kit!  This is a software
	package that accompanies the book, Practical File System Design, which
	Dominic Giampaolo wrote and is published by Morgan Kaufmann (ISBN
	1558604979).

	This package is a very simple framework in which you can experiment
	with a working (but simple) file system implementation.  The framework
	is designed so that you can go in and modify one part of it, such as
	how the used and free disk blocks are managed, and not have to touch
	the rest of the file system.  And because the package creates its file
	system inside of a normal file on your hard disk, you don't have to
	have a spare disk or require special (root) privileges to run the
	program.  The goal is that this package should provide a convenient
	test bed for trying out new file system ideas without having to go
	through the pain and difficulty of creating a real kernel based file
	system.  The API is generic enough however that after an you debug
	your implementation within this framework it could be moved to a real
	kernel based file system for the BeOS or a Unix like operating system.

This package has a "no commercial use" licence.
