 There are some significant "warts" in this; such as accepting a ticket sets it to 'assigned' state, and assigning a ticket sets it to 'new' state.  Perfectly obvious, right?
-So you will probably want to migrate to "basic" workflow; `contrib/workflow/migrate_original_to_basic.py` may be helpful.

 == Basic Ticket Workflow Customization ==
+
+Note: Ticket "statuses" or "states" are not separately defined. The states a ticket can be in are automatically generated by the transitions defined in a workflow. Therefore, creating a new ticket state simply requires defining a state transition in the workflow that starts or ends with that state.
 
 Create a `[ticket-workflow]` section in `trac.ini`.

 After you have changed a workflow, you need to restart apache for the changes to take effect. This is important, because the changes will still show up when you run your script, but all the old workflow steps will still be there until the server is restarted.

+== Example: Add simple optional generic review state ==
+
+Sometimes Trac is used in situations where "testing" can mean different things to different people so you may want to create an optional workflow state that is between the default workflow's `assigned` and `closed` states, but does not impose implementation-specific details. The only new state you need to add for this is a `reviewing` state. A ticket may then be "submitted for review" from any state that it can be reassigned. If a review passes, you can re-use the `resolve` action to close the ticket, and if it fails you can re-use the `reassign` action to push it back into the normal workflow.
+
+The new `reviewing` state along with its associated `review` action looks like this:
+
+{{{
+review = new,assigned,reopened -> reviewing
+review.operations = set_owner
+review.permissions = TICKET_MODIFY
+}}}
+
+Then, to integrate this with the default Trac 0.11 workflow, you also need to add the `reviewing` state to the `accept` and `resolve` actions, like so:
+
+{{{
+accept = new,reviewing -> assigned
+[…]
+resolve = new,assigned,reopened,reviewing -> closed
+}}}
+
+Optionally, you can also add a new action that allows you to change the ticket's owner without moving the ticket out of the `reviewing` state. This enables you to reassign review work without pushing the ticket back to the `new` status.
+
+{{{
+reassign_reviewing = reviewing -> *
+reassign_reviewing.name = reassign review
+reassign_reviewing.operations = set_owner
+reassign_reviewing.permissions = TICKET_MODIFY
+}}}
+
+The full `[ticket-workflow]` configuration will thus look like this:
+
+{{{
+[ticket-workflow]
+accept = new,reviewing -> assigned
+accept.operations = set_owner_to_self
+accept.permissions = TICKET_MODIFY
+leave = * -> *
+leave.default = 1
+leave.operations = leave_status
+reassign = new,assigned,reopened -> new
+reassign.operations = set_owner
+reassign.permissions = TICKET_MODIFY
+reopen = closed -> reopened
+reopen.operations = del_resolution
+reopen.permissions = TICKET_CREATE
+resolve = new,assigned,reopened,reviewing -> closed
+resolve.operations = set_resolution
+resolve.permissions = TICKET_MODIFY
+review = new,assigned,reopened -> reviewing
+review.operations = set_owner
+review.permissions = TICKET_MODIFY
+reassign_reviewing = reviewing -> *
+reassign_reviewing.operations = set_owner
+reassign_reviewing.name = reassign review

-This is becoming a frequent request, with clear usecases.  The closest the current implementation will allow is to have a plugin provide a `triage` action that sets the next state based on the ticket type, so a `new` ticket would move to `new_task`, `new_defect`, etc., and the workflow graph would separate at that point.
