The heart of WTF is the modules. A module is a discreet unit of functionality that extracts data from some source and packages that data for display.
For example, the New Relic module uses New Relic’s API to retrieve a list of the latest deploys and packages that information as a list for display in the “New Relic” widget.
The Clocks module takes a list of timezones and packages that information as a list of city/time pairs for display in the “Clocks” widget.
