+Feature: Command Line Processing
+  As a source code writer I want to be able to
+  call PDD as a command line tool
+
+  Scenario: Help can be printed
+    When I run bin/pdd with "-h"
+    Then Exit code is zero
+    And Stdout contains "Usage: pdd"
+
+  Scenario: Simple puzzles collecting
+    Given I have a "Sample.java" file with content:
+    """
+    public class Main {
+      /**
+       * @todo #13 Let's do it later, dude
+       *  or maybe even never :)
+       */
+      public void main(String[] args) {
+        // later
+      }
+    }
+    """
+    When I run bin/pdd with "-v -s . -f out.xml"
+    Then XML file "out.xml" matches "/puzzles[count(puzzle)=1]"
