No module should be considered complete unless it contains documentation regarding how to operate it. Documentation for a module exists within the module itself, in special variables called DOCUMENTATION, EXAMPLES, and RETURN.
The DOCUMENTATION variable contains a specially formatted string describing the module name, the version that was added to Ansible (if it is in Ansible proper), a short description of the module, a longer description, a description of the module arguments, author and license information, additional requirements, and any extra notes useful to users of the module. Let's add a DOCUMENTATION string to our module under the existing import shutil statement:
import shutil DOCUMENTATION = ''' --- module: ...
