+module: jenkins_script
+short_description: Executes a groovy script in the jenkins instance
+version_added: '2.3'
+description:
+    - The M(jenkins_script) module takes a script plus a dict of values
+      to use within the script and returns the result of the script being run.
+
+options:
+  script:
+    description:
+      - The groovy script to be executed.
+        This gets passed as a string Template if args is defined.
+    required: true
+    default: null
+  url:
+    description:
+      - The jenkins server to execute the script against. The default is a local
+        jenkins instance that is not being proxied through a webserver.
+    required: false
+    default: http://localhost:8080
+  validate_certs:
+    description:
+      - If set to C(no), the SSL certificates will not be validated.
+        This should only set to C(no) used on personally controlled sites
+        using self-signed certificates as it avoids verifying the source site.
+    required: false
+    default: True
+  user:
+    description:
+      - The username to connect to the jenkins server with.
+    required: false
+    default: null
+  password:
+    description:
+      - The password to connect to the jenkins server with.
+    require: false
+    default: null
+  args:
+    description:
+      - A dict of key-value pairs used in formatting the script.
+    required: false
+    default: null
+
+notes:
+    - Since the script can do anything this does not report on changes.
+      Knowing the script is being run it's important to set changed_when
+      for the ansible output to be clear on any alterations made.
