I am in the process of building my first Rails application (Gradesheet) and would like a little advice on assigning a license. Even though most Rails projects are MIT licensed the chosen license for this application is GPL-2, which I think covers my needs pretty well. The reason I'm asking this list is that I want to, one day, package this application up for use in Debian and I want to make sure everything goes as smoothly as possible.
My question is what is the best way to apply this license to my project? I know that I could copy the GPL-2 header into each of my files, but that is very repetitive and wasteful of storage and screen space. My thought was just to put a license section in the README.rdoc or make a LICENSE.rdoc file that says something like "this project is licensed under GPL-2, except otherwise explicitly noted." Would that satisfy the Debian packaging requirements? If not, what do I have to do?
