+//
+// This class handles payment requests from clicking on
+// bitcoin: URIs
+//
+// This is somewhat tricky, because we have to deal with
+// the situation where the user clicks on a link during
+// startup/initialization, when the splash-screen is up
+// but the main window (and the Send Coins tab) is not.
+//
+// So, the strategy is:
+//
+// Create the server, and register the event handler,
+// when the application is created. Save any URIs
+// received at or during startup in a list.
+//
+// When startup is finished and the main window is
+// show, a signal is sent to slot uiReady(), which
+// emits a receivedURL() signal for any payment
+// requests that happened during startup.
+//
+// After startup, receivedURL() happens as usual.
+//
+// This class has one more feature: a static
+// method that finds URIs passed in the command line
+// and, if a server is running in another process,
+// sends them to the server.
