The ccal utility is a simple-to-use command line program which writes
a Gregorian calendar together with Chinese Lunar calendar to standard
output.

Its usage is similar to the cal program generally available on Unix
platforms.

In addition to console output, it can also generate Encapsulated
Postscript and HTML table outputs for use in do-it-yourself calendars
and web pages.

It supports both simplified and traditional Chinese characters.
