How do I know which GWT modules I need to inherit?

To minimize complexity and compilation times, GWT's libraries are broken up into modules that contain various functionality.  For example, there is a module for JSON support, and a separate module for the HTTP RequestBuilder functionality.  If you want to use a given piece of functionality, you must include the appropriate module via an <inherits> tag in your project's XML file.

Since it can be difficult to remember which module includes which functionality, the table below summarizes the available modules.
