4.7 The Engine Tag

The query "example engine" produces a response similar to "It is 9:18 UTC on April 12, 2008." (but with the current time and date). In this case, the query is matched to the match pattern "engine," which terminates in an "engine" tag that references a cgi program running on the DOTGO servers. An engine is any web-based application program and can return arbitrary output in response to arbitrary input. Here the engine simply returns the current time and date.
