Non-Networked File System 2.1.9

Non-Networked File System provides a consistent file system over several non networked UNIX computers (or slow networked). For example on your computer at home and at work using only a floppy disk for the synchronisation.
Main features:
- You are sure to work on the latest version of files.
- You dont need to remember which files are modified on an host and must be transfered on others.
- You dont need to made backup, because if a computer crash the file system is still on the other computers working with NNFS.
- The NNFS medium is choosen by a user shell script, it could be: floppy disk, usb key, serial connection, ...
- Minimal NNFS medium bandwidth to make the updates.
- EASY TO USE: Running ``nnfs command before and after your work.
- Numbered backup of files modified/deleted on NNFS.
- If you modify the same file on several hosts NNFS solves the update conflict.
- The program has been hugely tested.
Enhancements:
- This release fixes the case where the user modifies a file mode while NNFS is running and NNFS is configured in order that a file mode change does not imply file synchronization.
