/* 99 Bottles of Beer in Rel.  

   Rel implements an extended subset of Date and Darwen's "Tutorial D" 
   true relational database language.

   This example (unecessarily and inefficiently) creates a relation variable
   to hold the bottles, which provides an opportunity to demonstrate 
   some of the built-in relational operators.
