Wallaby updates

Information about the Wallaby configuration service for Condor pools.

The Wallaby API

This is the Wallaby API version 20101031.1, which was released as part of Wallaby 0.10.0 on December 14, 2010. (For older versions of the API, please see here for the 0.9.x API and here for the 0.3.x API.) The API has a major version and a minor version; successive minor versions may add methods and properties but not change or remove existing members.
