 SWH-loader-dir
 ==============
 
 The Software Heritage Directory Loader is a tool and a library to walk a local
 directory and inject into the SWH dataset all unknown contained files.
 
 
 Directory loader
 ================
 
 
 ### Configuration
 
 This is the loader's (or task's) configuration file.
 
 loader/dir.yml:
 
     storage:
       cls: remote
       args:
         url: http://localhost:5002/
 
     send_contents: True
     send_directories: True
     send_revisions: True
     send_releases: True
     send_occurrences: True
     # nb of max contents to send for storage
     content_packet_size: 100
     # 100 Mib of content data
     content_packet_block_size_bytes: 104857600
     # limit for swh content storage for one blob (beyond that limit, the
     # content's data is not sent for storage)
     content_packet_size_bytes: 1073741824
     directory_packet_size: 250
     revision_packet_size: 100
     release_packet_size: 100
     occurrence_packet_size: 100
 
 Present in possible locations:
 - ~/.config/swh/loader/dir.ini
 - ~/.swh/loader/dir.ini
 - /etc/softwareheritage/loader/dir.ini
 
 
 #### Toplevel
 
 Load directory directly from code or toplevel:
 
-    from swh.loader.dir.tasks import LoadDirRepository
+    from swh.loader.dir.loader import DirLoader
 
     dir_path = '/path/to/directory
 
     # Fill in those
-    origin = {}
+    origin = {'url': 'some-origin', 'type': 'dir'}
+    visit_date = 'Tue, 3 May 2017 17:16:32 +0200'
     release = None
     revision = {}
     occurrence = {}
 
-    LoaderDir().load(dir_path, origin, revision, release, [occurrence])
+    DirLoader().load(dir_path, origin, visit_date, revision, release, [occurrence])
 
 
 #### Celery
 
 Load directory using celery.
 
 Providing you have a properly configured celery up and running
 
 worker.ini needs to be updated with the following keys:
 
     task_modules = swh.loader.dir.tasks
     task_queues = swh_loader_dir
 
 cf. https://forge.softwareheritage.org/diffusion/DCORE/browse/master/README.md
 for more details
 
 You can send the following message to the task queue:
 
     from swh.loader.dir.tasks import LoadDirRepository
 
     # Fill in those
-    origin = {}
+    origin = {'url': 'some-origin', 'type': 'dir'}
+    visit_date = 'Tue, 3 May 2017 17:16:32 +0200'
     release = None
     revision = {}
     occurrence = {}
 
     # Send message to the task queue
-    LoaderDir().load(('/path/to/dir,
-                     origin,
-                     revision,
-                     release,
-                     [occurrence]))
+    LoaderDirRepository().run(('/path/to/dir, origin, visit_date, revision, release, [occurrence]))
