This software uses the MoreFiles library 1.2.2 by Jim Luther (Apple Macintosh Developer Technical Support).
The MoreFiles notice says:

**	responsibility for its operation is 100% yours.  However, what you are
**	not permitted to do is to redistribute the source as "DSC Sample Code"
**	after having made changes. If you're going to re-distribute the source,
**	we require that you make it clear in the source that the code was
**	descended from Apple Sample Code, but that you've made changes.

Since I made changes (the MoreFiles routines are compiled with C instead of Pascal calling conventions), as a safeguard against Apples lawyers I chose not to redistribute the Apple code at all; you will have to download the latest version yourself, should you need it.
