Title: ARQ - Building Queries Programmatically It is possible to build queries by building and abstract syntax tree (as the parser does) or by building the algebra expression for the query.  It is usually better to work with the algebra form as it is more regular. See the examples in the ARQ `src-examples/` directory of the ARQ distribution, particularly `arq.examples.AlgebraExec`.
