  <strong>OsxAdminPassword</strong>
  <p>Title: Check administartor authentication on Mac OS-X </p>
  <p>Description: Gets path of the AppleScript file at install time and
  a different path to the AppleScript at uninstall time.
  OsxAdminPassword  Activates an AppleScript, in a Shell,
  that triggers the first sudo command with prompt for authentication.
  If the right password was entered the installation gets 5 minutes of
  enabling sudo commands hassle-free (without asking for authentication again).
  This action enables three fail tries before canceling the installation.
  In case of three mistakes or a cancel button pressed,
  this action cancels the installation.
  <p>A hidden parameter - authentication holds the result:
  <br>Success: authentication = 0.</br>
  <br>Fail (wrong or error): authentication = 1.</br>
  <br>Canceled by the user: authentication = -1.</br>
  <br>This value can be checked for appropriate ‘Finish’ dialog.</br></p>
  <p>In case of fail OsxAdminPassword sends message to the installation log.
  OsxAdminPassword checks the input-stream for a return value by the
  AppleScript file and according to this return-value decides if to cancel the
  installation and what value to set the authentication property to.
  Usually the AppleScript is installed to $D(temp) in installation before
  the OsxAdminPassword  in the sequence. This file needs to be installed to a
  permanent folder if the installation continues, so it can be used during uninstall.
  At the end of the uninstall it has to be deleted explicitly.</p>
