+This is a utility to decode JSON data into text info.
+
+The 'multiline' mode assumes that each line in an input is a seperate and complete
+JSON record (ie no return characters in the middle of a record)
+
+Given a files with 
+
+{ "@id" : "Test_1" }
+{ "@id" : "Test_2" }
+{ "@id" : "Test_3" }
+
+Example:
+    value['@id']
+
+Prints out the file:
+    Test_1
+    Test_2
+    Test_3
