What is the difference between -dwtpversion and wtpversion?

Question

I am new to Maven. I am going to develop my first application with Maven. Therefore, reading the documentation, I foundmvn eclipse:eclipse -Dwtpversion=2.0

I know WTP is a "web tool platform", but what is it -Dwtpversion? I searched the Internet but found nothing.
