+    Demo Frame For Screen Captures
+
+    This program can be used to help you record videos.
+
+    Because it relies on the "transparent color" feature that's only available on Windows, this Demo is only going
+    to work the indended way on Windows.
+
+    Some video recorders that record a portion of the screen do not show you, at all times, what portion of the screen
+    is being recorded.  This can make it difficult for you to stay within the bounds being recorded.
+    This demo program is meant to help the situation by showing a thin line that is 20 pixels larger than the area
+    being recorded.  
+
+    The top edge of the window has the controls.  There's an exit button, a solid "bar" for you to grab with your mouse to move
+    the frame around your window, and 2 inputs with a "resize" button that enables you to set the frame to the size you want to stay
+    within.
