Is there a Bukkit Plugin that allows giving new users books?

I was thinking, with the books Minecraft has come out with, it's time to replace those 500 blocks worth of signs with a simple book. Is there a Bukkit Plugin that will automatically give new users a rulebook?

The BookRules plugin might be exactly what you are looking for:

Automatically give players written books containing rules, getting started guides, etc when they join your server.

It's pretty simple to use:

• in the config file set Seconds-Delay to a value you deem appropriate. (It's the time in seconds between a new player login and the book being given to the player)
• In game, write a book with all the rules
• use /rulebook add to add the book as a rule book.
• enjoy

A plugin that would be nice would be a book read plugin keeping all new player in prison as long as they haven't finished reading the rule book.

You can use the tools referred to in the answer to my question Is there a bukkit plugin to run small scripts when players (re)spawn?, namely Autorun command's
