It contains
* the "Features" section for the Refactor documentation;
* the removal of any reference to IKS project in every section and from
the image refactor.png.

## Features
-todo...
+In the Refactor rules are interpreted as [SPARQL
CONSTRUCT](http://www.w3.org/TR/rdf-sparql-query/#construct) queries in which
+the premises (the left part before the arrow in the rule) are the WHERE
clause, while the conclusion (the right part after the arrow in the rule) is
+translated into the construct template, i.e., triple patterns in conjunctive
form.
+
+As an example, we can take in account the following rule:
+
+ prefix kn = <http://foo.org/kinship#> .
+ uncleRule[ has(kn:parent, ?x, ?y) . has(kn:sibling, ?y, ?z) ->
has(kn:uncle, ?x, ?z) ]
+
+The rule above is transformed into the following SPARQL CONSTRUCT query:
+ PREFIX kn: <http://foo.org/kinship#>
+ CONSTRUCT { ?x kn:uncle ?z }
+ WHERE {
+ ?x kn:parent ?y .
+ ?y kn:sibling ?z
+ }
+
+The SPARQL engines used internally by the Refactor for running rules is
[Apache Jena ARQ](http://incubator.apache.org/jena/documentation/query/)
+We remand any detail about the syntax and the expressivity of the Stanbole
Rule language to its [section](./language.html).
