+\fBTcl_SetMainLoop\fR allows setting an event loop procedure to be run.
+This allows, for example, Tk to be dynamically loaded and set its event
+loop. The event loop will run following the startup script. If you
+are in interactive mode, setting the main loop procedure will cause the
+prompt to become fileevent based and then the loop procedure is called.
+The main loop procedure must have an interface that matches the type
