+This tool is based on UNIX shell command comm. It compares two datasets and returns similarities or differences. For example, if you have two datasets::
+  
+ a  1
+ b  2
+ c  3
+
+and::
+
+ a  1
+ f  6
+ h  8
+
+Using this tool with **Lines unique to Dataset1** option will return::
+
+ b  2
+ c  3
+
+If you use **Lines shared between Dataset1 and Dataset2** option output will look like this::
+
+ a  1
