[Eug-lug] What program in linux can synchronized my Laptop "projects" with my usb flash ram stick?

[Harald Sundt]

Greetings

My goal is to have the latest versions of OpenOffice files I am working 
on my Mac Tower, my Linux laptop, and the USB flash ram stick I use to 
ferry files back and forth.

I have a laptop running fedora. I have a tower Mac Intel Pro.

I ferry files back and forth on a cruiser scan disk USB stick.

I have a folder on my Mac called 'projects' which I synchronize with a 
file called 'projects' on  my transport stick using Personal Backup on 
the Mac.

As you can guess, I have a file folder called 'projects" on my linux laptop.

What program in linux can synchronized my Laptop "projects" with my usb 
flash ram stick folder called "synchronize"?


Thanks

Hal
