You need to decide whether your package should display a copyright message while it is being installed. If so, create the copyright file.
You should include a copyright file to provide legal protection for your software application. Check with the legal department of your company for the exact wording of the message.
To deliver a copyright message, you must create a file named copyright. During installation, the message is displayed exactly as it appears in the file (with no formatting). See the copyright(4) man page for more information.
Be certain that your copyright file has an entry in the prototype file. The file type should be i (for package information file).
