+endpoints over HTTP.  It has been intentionally designed to 'feel' similar to
+tools for interrogating SQL databases.  For example, you can enter a query over
+several lines, using a semi-colon at the end of a line to indicate the end of
+your query.  It also supports readline so that you can more easily recall and
+edit previous queries, even across sessions.  It can be used non-interactively,
+for example from a shell script.")
