+# Essence Of Zen
+
+# This program essentially takes in your entered directory and changes any specified extension
+# with another extension specified.
+
+# To-Do =========
+# *Add Menu
+# *Add more user-proofing
+# *Create a GUI?
+
+
+import os
+
+# Global Variables ===========================
+VERSION = "1.3.1" # A variable to call for showing update once menu is made
+
