A meta-search engine.
NOTE: topiary is currently alpha-quality software! It's not meant for general purpose usage yet. Large pieces of functionality are broken or missing, and custom data probably won't work from one version to the next.
Topiary is a meta-search engine. Topiary can direct your queries to external search engines, or syndicate and aggregate data from search engines that provide XML or JSON APIs.
For advanced users, Topiary can be used as a more general-purpose API client. In future versions, users will be able build and customize their own sources to syndicate data from.
