There is a new `set' command that should make things easier for new players,
and hopefully for old players alike.

Do `help set' to see all the options. In particular, notice that you can
view options by keywords now, and interactive mode is now documented.

Also note that some of the setting names have changed: For example, "noecho"
has been renamed to "echo", and it defaults to on instead of off.

If you find bugs, please direct them to me. I have renamed the original
`set' to `oldset', but it will be removed entirely after any bugs are ironed
out with the new `set'.
