A simple problem

It usually starts with a single task to be done. Single, simple that can be done by hand. For instance, I try to add a three-lines header for each file of any projects I work on.

Even though, I almost work under MIT, I like the idea that someone could stumble upon my code and will immediatly look for the rest of the project. Well, I did it in the past, so I like the idea. The main problem is the lack of discipline, in all projects (without any exception) I forgot some headers.
