-The backstory of this is that SDL on Pandora console was suffering from tearing
-and stuttering problems because SDL default x11 driver doesn't work that well
-there. Almost 6 months have passed after pandora's release, no improved
-SDL versions appeared (not blaming anyone here, pandora's availability was low
-and there where were several SDL improvement in the works though). This
-encouraged me to create this quick version until something better appears
-(if ever).
+Features:
+
+ * hardware scaling support (up and down)
+ * doublebuffering support (can eliminate tearing)
+ * vsync support (can give smooth scrolling if done right)
+ * keymap change with a config file
+ * 16/24/32bpp display support
+ * touchscreen input translation to scaler source image coordinates
+ * screen surface cropping / border removal support
+
+Caveats:
+ * disabled by default (falls back to x11/fbcon SDL drivers) unless
+ SDL_VIDEODRIVER environment variable is set
+ * no windowed mode support, fullscreen only
+ * requires functional DSS2 driver with /dev/fb1 mapped to overlay1 or
+ overlay2 and enough free VRAM available for requested display mode.
