Turning off "created by" stamp when generating files in IntelliJ

In IntelliJ 13 and above it is in the File and Code Templates area of the settings dialog. In Idea 15+ you can get there by typing ctrl+shift+A on windows or cmd+shift+A on osx and then typing Include Templates in the popup action search dialog. There should be a tab called Includes on which you will find the Java and ActionScript file types, and the text can simply be removed completely if you like.

But, in more recent versions of IntelliJ things have got quite a bit easier. The first time it generates this stuff, put your cursor in the generated comments and hit alt-enter (or the equivalent according to your key-mapping preferences) to bring up the 'fix' options, and select 'edit template'. This will bring you right to the setting that needs to be updated. Simply remove all the text (or replace it with something more palatable to you), hit enter and you're done.
