+/// This file provides macros for easier construction of openCypher query AST.
+/// The usage of macros is very similar to how one would write openCypher. For
+/// example:
+///
+/// AstStorage storage; // Macros rely on storage being in scope.
+/// // PROPERTY_LOOKUP and PROPERTY_PAIR macros
+/// // rely on a DbAccessor *reference* named dba.
+/// database::GraphDb db;
+/// auto dba_ptr = db.Access();
+/// auto &dba = *dba_ptr;
+///
+/// QUERY(MATCH(PATTERN(NODE("n"), EDGE("e"), NODE("m"))),
+/// WHERE(LESS(PROPERTY_LOOKUP("e", edge_prop), LITERAL(3))),
+/// RETURN(SUM(PROPERTY_LOOKUP("m", prop)), AS("sum"),
+/// ORDER_BY(IDENT("sum")),
+/// SKIP(ADD(LITERAL(1), LITERAL(2)))));
+///
+/// Each of the macros is accompanied by a function. The functions use overload
+/// resolution and template magic to provide a type safe way of constructing
+/// queries. Although the functions can be used by themselves, it is more
+/// convenient to use the macros.
