What does @ means for permissions?

Guys,

My question is regarding to file permission on Mac OS X 10.7.
I wrote an script which should pick XML files from a folder. But when we copy the files to that particular folder, the script skip the files I guess because of permission, If we open the files and save it them the script works.

Initially the files has this set of permission:
-rw-r--r--+ 1 admin todos 585 (in this case the script does not works)

after open and save the file.

-rw-r--r--@ admin todos 582

I know that + means that the file permission is a ACL involve.

But I do not know what the @ means at the end after the file is save and what change in the file permission

thanks in advance
