[plug] Vaction program and multiple aliases

[Joel at Plug]

Have just added the vacation program to our mail server and just 
wondering if anyone out there can answer one question : How does one add 
multiple aliases to the users' .forward file?

Is it with multiple -a parameters (one for each alias)? Or is it 
comma-separated like "-a alias1, alias2"?

Or is multiple aliases even possible?

The man page doesn't even mention that the parameters must go in the 
.forward file and google just seems to be listing sites  that for the 
most part are just re-hashing the man page.
