    $$ZIPFILE

  from 

    $$RELEASE

  You need to take additional steps to complete installation.

  Your operating systems' security policied need to "allow" 
  running programs from $$PACKAGE.

  Example: on macOS you can type open the programs in finder.

      open $$HOME/bin

  Find the program(s) and right click on the program(s)
  installed to enable them to run.
