-This type of application is constructed by creating a function that
-gets invoked by the framework. Typically that function contains a
-`while (something)` event loop. If the function returns, the Xapp
-stops. In this type of Xapp, the Xapp must fetch its own data, either
-from RMR, SDL or other source. The framework does less work for a
-general application compared to a reactive application. The framework
-sets up an RMR thread and an SDL connection, then invokes the
-client-provided function.
+This type of application is constructed by creating a single function
