 # Vs. battle intro animation
+# If you want to add a custom battle intro animation, copy the code below for
+# the Vs. animation and adapt it to your own. The register call has 4 arguments:
+#    1) The name of the animation. Typically unused, but helps to identify an
+#       animation.
+#    2) The animation's priority. If multiple special animations could trigger
+#       for the same battle, the one with the highest priority number is used.
+#    3) A condition proc which decides whether the animation should trigger.
+#    4) The animation itself. Could be a bunch of code, or a call to, say,
+#       pbCommonEvent(20) or something else. By the end of the animation, the
+#       screen should be black.
+# Note that you can get an image of the current game screen with
+# Graphics.snap_to_bitmap.
