Howto Install Java Native Access Modules
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The 'Java Native Access' - *JNA* - modules are required 
by some of the basic prerequired modules of the author
for *Jython* on *Windows* systems.
For example for *platformids*.
The installation is simply done by copying the required modules, see also [JNA]_.

For example in case of *Windows-10* with the native *OpenSSH* server:

   .. parsed-literal::  
   
      rsync -avHPS  \\
        jna.jar \\
        jna-platform.jar \\
        win32-x86-64.jar \\
        --rsync-path='c:\\\\cygwin64\\\\bin\\\\rsync.exe' \\
