+    Get the input elements that will be transformed into tasks in a generic
+    way.  The elements themselves are free-form, and become the input to the
+    first transform.
+
+    By default, this reads jobs from the `jobs` key, or from yaml files
+    named by `jobs-from`.  The entities are read from mappings, and the
+    keys to those mappings are added in the `name` key of each entity.
+
+    If there is a `job-defaults` config, then every job is merged with it.
+    This provides a simple way to set default values for all jobs of a kind.
+    The `job-defaults` key can also be specified in a yaml file pointed to by
+    `jobs-from`. In this case it will only apply to tasks defined in the same
+    file.
+
+    Other kind implementations can use a different loader function to
+    produce inputs and hand them to `transform_inputs`.
