Batch Cmd documentation

Is there documentation on the Batch API functions? Or at least a list of which Commands work with Batch?

I need to create a lot of work orders (2000ish) and would rather not send 2010 API calls.
I have a functioning API that can create a single work order.
I have a functioning API using the BATCH URL with CostStatusChangeCommand.

I can test adapting the single WoCreateCommand call into a call to Batch/Cmd following the format of the working CostStatusChangeCommand call, but I want to make sure that is possible before setting aside time for that testing.

In other news, the search field is no longer present on these pages. Is that a temporary thing, or should I get used to it =D
