[galaxy-commits] commit/galaxy-central: greg: Add a Tool Shed API script that can be used to retrieve the current set of categories from a Tool Shed (e.g. the test Tool Shed) and create each of them in a local development Tool Shed. This script can be used to streamline the process of creating a new development Tool Shed, populating it with categories expected in a public Tool Shed, and creating a new repository hierarchy that can be exported into a capsule and imported into the public Tool Shed.
