For a Chinese introduction of this package, read this blog entry.
Fortune-zh_osx brings Chinese Tang and Song dynasties poems to the old fortune game. Three hundred Tang poems and one hundred Song poems are included. Running "fortune-zh" command, a random Chinese poem will be shown. Using the AppleScirpt file in the package you can create mails using those poems as signature.
Fortune-zh_osx is based on the Debian package fortune-zh maintained by Yu Guanghui.

NOTE: To use this package, you should already have a runnable fortune application. You can download one here and compile it by yourself. And your terminal should display Chinese characters correctly. See this HOWTO to make this.
