extended attributes on files

[Tom Allison]

I have some files that I backed up to a Linux box via 'rsync -av'
and restored them later on.

But they can't be used by the intended application.

the only difference I can find is that the usable files I have created 
have a permissions of rwxr--r--@

And ls - at l returns something to this affect:
	com.apple.FinderInfo	32
	com.apple.ResourceFork	730

I am under the believe that if I can apply these extensions to the 
original files that I will be able to use them.  But I have no idea 
where to start.  These things are not in chmod.

help?
hints?
