+** File: winevent.c
+** Description: Test functions in plevent.c using Windows
+**
+** The winevent test exercises the PLEvent library in a maner
+** similar to how the Mozilla (or NGLayout) Client will use
+** it in a Windows environment.
+**
+** This test is based on ideas taken from Charles Petzold's
+** book "Programming Windows 3.1". License to use is in the
+** book. It has been ported to Win32.
+**
+** Operation:
+** The initialization is a standard Windows GUI application
+** setup. When the main window receives its WM_CREATE
+** message, a child window is created, a edit control is
+** instantiated in that window.
+**
+** A thread is created; this thread runs in the function:
+** TimerThread(). The new thread sends a message every second
+** via the PL_PostEvent() function. The event handler
+** HandlePadEvent() sends a windows message to the edit
+** control window; these messages are WM_CHAR messages that
+** cause the edit control to place a single '.' character in
+** the edit control.
+**
+** After a deterministic number of '.' characters, the
+** TimerThread() function is notified via a global variable
+** that it's quitting time.
+**
+** TimerThread() callse TestEvents(), an external function
+** that tests additional function of PLEvent.
