INTRODUCTION
------------
When sharing your online life over several PCs (that cannot talk to each 
other), it would be usefull to be able to keep working files up-2-date 
on each machine. This project is designed to offer a product that will keep an
offline mobile device (such as a USB stick) updated with changes made to file 
on several machines. 


USE CASE
--------
1. You create a document on your laptop.
2. In the evening you want to work on this file at home.
3. The the next day, you work on the file at work.
4. Later you add some more changes on your laptop.

In the above example, their would need to be a lot of manuel file copying
between different locations. By using this product (by pluggin in a USB stick 
each time you use a PC) the correct file is always copied onto your working 
machine. Further, if you hadn't "syncronised" between 3 and 4, then your laptop
version would be out of date and you couln't work on it. But devSync will be 
able to handle this, leaving you free to make changes to the old copy of the 
laptop file. Later when you do sync, devSync sees that the copy on the laptop 
was an old file and that you have made additional changes to it. It therefor 
"feeds in" earlier changes (2 and 3), then adds your final changes to the list. 
If the changes you made were in a simmilar area, then devSync lets the user 
decide which changes take president. This way you can work on any file at any 
time and be sure your not going to loos things.
