Lightweight and Unobtrusive

I consider this a "lightweight", unobtrusive plugin for two reasons:

1. Your WP blog is not modified in any way. All existing and future entries will look exactly the same. You can choose to modify the "more" text passed to the_content to reflect the new behavior (e.g. "View the rest of this entry right here") if you choose, but that is entirely up to you.
2. There are no "options" or any other modifications to your WP database. If deactivated and deleted, this plugin will leave no trace of itself behind.
