Query language
==============

Circolog uses a sql-inspired query language. If you know SQL, then you can use
"where clauses" in circolog. If you don't know SQL, don't worry: the language
is easy enough for you to learn the most basic queries without worrying too
much.

You can only filter the rows, you can't sort them or group them in any way.
