[OS X TeX] Keeping TeX installations synchronized between machines

[Alessandro Andretta]

Dear All, 

could you explain what a sym link is? and, more importantly how to set it up? 
I am using my iDisk to sync my documents between computers. 
I tried to put an alias in ~/Library/texmf pointing to the files on the iDisk, but did not work.

Also, I would really love to be able to sync the CommandoCompletion files in TeXShop.

Thanks in advance,
