Hi Kamil,

Thank you for your valuable input. It seems a good idea to use it in the next release. 

Cheers,

Pull request is waiting to be merged into main Casks repository: https://github.com/caskroom/homebrew-cask/pull/7116, so it will be posssible to download and install Cmpl by simply running `brew cask install cmpl`.

Furthermore, installer assumes that current directory is the one where installer is. To solve that issue I added the line to ensure CWD is correct. What is more, it does “cd ..; cp Cmpl /Applications/“ – here is the assumption, that the directory is named Cmpl. In my case, as I had already Cmpl directory in my Downloads, the Unarchiver extracted new version to Cmpl-2, so I ended with “new” installer installing old binaries. You can find fixed version of installer and deinstaller on Gist https://gist.github.com/kfigiela/69d246a68c8028aef33d. Possibly, Linux scripts may also require similar fixes.
