title: Add JavaDoc @author tag to every java file in my project
body: <p>I hava a Java project with a lot of files. In some of this I inserted a JavaDoc @author tag just before class/interface declaration, but not in all. I would like a script (bash, perl, whatever) able to add @author tag in the right position (just before class declaration) for all files that doesn't have one. Ho to find the right line where to add this javadoc?:</p>
