It does it by default, but I don't think it does that properly with damaged zip 
archives. That was the reason I had to switch from using clamd to clamscan. 
clamd was dying every time scanning damaged zip archive. And builin rar 
archives support works only with files arrchived with rar 2.0.
So, why not use all external archivers to examine all kind of archives?
And one more clamscan option I missed last time:  --mbox
I think it make sense to add that too.

Best regards,
