If the port needs to execute commands when the binary
      package is installed with pkg add or
      pkg install, use
      pkg-install.  This script will
      automatically be added to the package.  It will be run twice by
      pkg, the first time as ${SH}
	pkg-install ${PKGNAME} PRE-INSTALL before the
      package is installed, and the second time as
      ${SH} pkg-install ${PKGNAME}
	POST-INSTALL after it has been installed.
      $2 can be tested to determine which
      mode the script is being run in.  The PKG_PREFIX
      environmental variable will be set to the package installation
      directory.
This script is here to help you set up the package so that it is as ready to use as possible. It must not be abused to start services, stop services, or run any other commands that will modify the currently running system.
