changed the script to use 
for ARCHIVE in "${@}" 
in case you give it another look after the release.

Instead of posting the changed version into pastezone, for now I'll leave you
with a link to my changed .zshrc because I still have hope that I will find the
time to improve upon that big ugly if else fi block somewhen in the future.
