 Csistck is a small Perl framework for writing scripts to maintain system configuration and consistency. The focus of csistck is to stay lightweight, simple, and flexible.
 
+h1. EXTENDING ROLES
+
+Roles can be defined using the @role@ keyword syntax, however a more flexible method is to extend a new object from Csistck::Role:
+
+<pre>
+    use Csistck;
+    use base 'Csistck::Role';
+
+    sub defaults {
+        my $self = shift;
+        $self->{config} = '/etc/example.conf';
+    }
+
+    sub tests {
+        my $self = shift;
+        $self->add(pkg({
+            dpkg => 'test-server',
+            pkg_info => 'net-test'
+        }),
+        template('files/example.conf', $self->{config}, { example => $self });
+    }
+
+    1;
+</pre>
+
+See Csistck::Role for information on extending roles
