License Clarification

[PanisSupraOmnia]

Hi, I maintain the AUR package for this project. While checking on a few things I noticed that it's unclear whether the script is licensed as GPL v2.0 only, or GPL v2.0 or later. Ideally, since you're using the GPL, the completion script should have a license header that specifies whether later versions may be used. See the license header instructions for details. Currently my package has it listed as the more restrictive GPL v2.0 only to be safe, but clarification would be appreciated so that I can make sure the metadata is accurate. Thank you!

@PanisSupraOmnia Hi. Due to personal reasons, currently I do not have time to maintain this project. I've set GPL license only because the previous maintainer used it. So we probably could use less strict version of GPL v2.0. I would be happy to review PR that fixes that.
