+CLI command: ckan shell
+-------------------------------
+The main goal to execute a ckan shell command is IPython session with the application loaded for easy debugging and dynamic coding.
+
+There are three variables already populated into the namespace of the shell:
+
+•	**app** containing the Flask application
+•	**config** containing the CKAN config dictrionary
+•	**model** module to access to the database using SQLAlchemy syntax
+
+**command:**
