 === Duplicated code analysis ===
 In large program systems often occure duplicated code, which is a computer programming term for a sequence of source code that occurs more than once. There are two ways in which two code sequences can be duplicates of each other: syntactically and functionally. This new feature can detect the syntactically similar duplicates. You can learn more about this topic and about the usage, especially about the command-line usage,  on [[DuplicateCodeAnalysis| Duplicate code analysis]] page.
+
+=== Clustering ===
+You can learn more about this topic on [[wiki:ModuleFunctionClustering]] page.
+
+You can use the clustering algorithm from {{{ri}}} by calling the {{{ri:cluster/0}}} function. You have to choose between agglomerative and genetic clustering at first and then between function and module clustering. Based on your choice {{{ri}}} will ask all of the parameters necessary for the clustering.
+
+Consider the following example:
+{{{
+ri:cluster().
+
+Please choose an item from the list (blank to abort).
+ 
+Please select an algorithm for clustering:
+ 1. Agglomerative
+ 2. Genetic
+ type the index of your choice: 1 
+Please choose an item from the list (blank to abort).
+ 
+Please select an entity type for clustering:
+ 1. function
+ 2. module
+ type the index of your choice: 2
+Please answer the following questions (blank to abort).
+ Module clustering with Agglomerative algorithm
+ Modules to skip(Type: none for default) none
+ Functions to skip(Type: none for default) none
+ Transform function(Select: [none,zero_one]) zero_one
+ Distance function(Select: [call_sum,weight]) weight
+ Antigravity(Type: 0.5 for default) 0.5
+ Merge Function(Type: smart for default) smart
+ Save results to database: (y/n) -> n
+}}}
+
+The result is:
