    $$ZIPFILE

  from

  You need to take additional steps to complete installation.

  Your operating system security policied needs 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.

  The man pages have been installed at '$$HOME/man'. You
  need to have that location in your MANPATH for man to
  find the pages. E.g. For the Bash shell add the
  following to your following to your '$$HOME/.bashrc' file.

      export MANPATH="$$HOME/man:$$MANPATH"
