 ## Location
 
 Either:
 - /etc/softwareheritage/loader/svn.ini
 - ~/.config/swh/loader/svn.ini
 - ~/.swh/loader/svn.ini

-This policy does not:
-- alter anything in regards of svn data
-- adds an extra-headers with repo uuid and svn revision. This permits to deal with update.

-## git-svn like
-
-For a git-svn like (ignore empty folder, no extra metadata, adapt
-user's name with repository's uuid, add extra commit line, no update
-policy), adapt to the previous options with the following:
-
-```txt
-with_policy = gitsvn
+check_revision: 10
 ```
 
-Notes:
-
-This policy does alter things:
-- it adds the repo-uuid on author's name (author@<repo-uuid>)
-- truncates date time commits so some precision is lost on date
-- removes empty folder if any are checkouted on disk 
-
-Those modifications, in effects, alter the git hash computation of
-revisions.
-
-This policy is destined for test. Thus:
-- no persistence takes place (even if send_* options are True)
-- no update is possible
-

-# Starting one instance
-
-## worker's configuration file
-
-The file is either at:
-- /etc/softwareheritage/worker.ini
-- ~/.config/swh/worker.ini
-- ~/.swh/worker.ini
-
 ## configuration content
 
 With at least the following module (swh.loader.svn.tasks) and queue
 (swh_loader_svn):
 
 
 ```
 [main]
 task_broker = amqp://guest@localhost//
-task_modules = swh.loader.svn.tasks,swh.loader.tar.tasks
-task_queues = swh_loader_svn, swh_loader_tar
+task_modules = swh.loader.svn.tasks
+task_queues = swh_loader_svn
 task_soft_time_limit = 0
 ```
 
 swh.loader.svn.tasks and swh_loader_svn are the important entries here.
 
 ## start worker instance
 
 To start a current worker instance:
 
 ```sh
 python3 -m celery worker --app=swh.scheduler.celery_backend.config.app \
                 --pool=prefork \
                 --concurrency=10 \
                 -Ofair \
                 --loglevel=debug 2>&1
 ```
 
 ## Produce a repository to load
 
-Either one repository:
+You can see:
+
+`python3 -m swh.loader.svn.producer svn --help`
+
+### one repository
 ```sh
-python3 -u -m swh.loader.svn.producer --svn-url file:///home/storage/svn/repos/pkg-fox
+python3 -u -m swh.loader.svn.producer svn --svn-url file:///home/storage/svn/repos/pkg-fox --visit-date 'Tue, 3 May 2017 17:16:32 +0200'
 ```
 
-or a bunch:
+Note:
+- `--visit-date` to override the default visit-date to now.
+
+### multiple repositories
+
 ```sh
-cat ~/svn-repository-list | python3 -m swh.loader.svn.producer
+cat ~/svn-repository-list | python3 -m swh.loader.svn.producer svn
 ```
 
-svn-repository is a list of svn repository urls (one per line).
-Something like:
+The file svn-repository-list contains a list of svn repository urls
+(one per line), something like:
+
 ```txt
-svn://svn.debian.org/svn/pkg-fox/
-svn://svn.debian.org/svn/glibc-bsd/
-svn://svn.debian.org/svn/pkg-voip/
-svn://svn.debian.org/svn/python-modules/
-svn://svn.debian.org/svn/pkg-gnome/
+svn://svn.debian.org/svn/pkg-fox/ optional-url
+svn://svn.debian.org/svn/glibc-bsd/ optional-url
+svn://svn.debian.org/svn/pkg-voip/ optional-url
+svn://svn.debian.org/svn/python-modules/ optional-url
+svn://svn.debian.org/svn/pkg-gnome/ optional-url
 ```
+
+## Produce archive of svndumps list to load
+
+see. `python3 -m swh.loader.svn.producer svn-archive --help`
