+/** @file glsync.c
+ * The program is simple: it paints a window alternating colors (red &
+ * white) either as fast as possible or synchronized to vblank events
+ *
+ * If run normally, the program should display a window that exhibits
+ * significant tearing between red and white colors (e.g. you might get
+ * a "waterfall" effect of red and white horizontal bars).
+ *
+ * If run with the '-s b' option, the program should synchronize the
+ * window color changes with the vertical blank period, resulting in a
+ * window that looks orangish with a high frequency flicker (which may
+ * be invisible). If the window is moved to another screen, this
+ * property should be preserved. If the window spans two screens, it
+ * shouldn't tear on whichever screen most of the window is on; the
+ * portion on the other screen may show some tearing (like the
+ * waterfall effect above).
+ *
+ * Other options include '-w <width>' and '-h <height' to set the
+ * window size.
