Create Gzipped Tar Archive Service for OS X 10.6 + 10.7

Although the tgz command line syntax is very simplistic, I’ve never managed to remember the exact flags for the command line interface. Additionally, if I’m clicking around in the Finder I don’t want to have to fall back to the command line to create a tgz archive. Inspired by this hint you can download a service to create a tgz archive that works with Snow Leopard and Lion.
