Lightning brings the Sunbird calendar to the popular email client, Mozilla Thunderbird. Mozilla Thunderbird is a redesign of the Mozilla mail component with the goal of becoming a cross-platform stand alone mail application using the XUL user interface language. See the Mozilla Thunderbird project page for more details. The Sunbird Project is a redesign of the Mozilla Calendar component. The goal is to produce a cross platform standalone calendar application based on Mozilla's XUL user interface language.
