Provide the help listing as default when no arguments are provided

When just writing "mvn" with no arguments on the command line I get a message such as this:
>mvn
[INFO] Scanning for projects...
[INFO] ----------------------------------------------------------------------------

Many new users to maven or any other such tools are used to getting at least some basic info of what is expected. How about just displaying the listing that shows up when a user writes "mvn -h" as default when no arguments are privided? This is also a feature that most other similar products have. I also would suggest printing a URL for where they can get basic information for how to use maven.
