If we have [apt-get](https://unix.stackexchange.com/questions/tagged/apt-get "show questions tagged 'apt-get'"), we might as well have [apt-cache](https://unix.stackexchange.com/questions/tagged/apt-cache "show questions tagged 'apt-cache'") and [apt-cdrom](https://unix.stackexchange.com/questions/tagged/apt-cdrom "show questions tagged 'apt-cdrom'"). Maybe we can make these symlinks to [apt](https://unix.stackexchange.com/questions/tagged/apt "show questions tagged 'apt'")?
