+4Pack of Simple CHDK Scripts
+============================
+
+Presented here are four simple scripts for Canon cameras using CHDK.  
+Each script is available in both the Lua and uBasic programming language. 
+Make sure you have your camera in "shooting mode" prior to activating these scripts.
+
+They are :
+
+1) shoot.bas & shoot.lua
+       - a very simple script that simply takes a picture after a configurable time delay
+
+2) interval.bas & interval.lua
+       - a script to continuously take pictures at a configurable time interval
+	   
+3) motion.bas & motion.lua
+       - a motion detection script - takes one picture when motion is detected 
+	   
+4) hdr.bas & hdr.lua
+       - a script for taking images used in high dynamic range pictures 
+	   - also called exposure bracketing
+	   - takes three picture - one correctly exposed, one overexposed and one underexposed
+	   
+Obviously these are very simple program and you are encouraged to modify and expand them to suit your needs.
+
