Comment:
As the `xlint` CI test shows, a proprietary license declaration requires use of `vlicense` in `do_install` or `post_install` to copy the license text into the package. As it stands, I see no license terms attached to this software. You should identify the license terms and be able to fetch the license text from somewhere so we know what terms govern the software.
