OPERATORS
     The primaries may be combined using the following operators.  The operators are listed in order of decreasing
     precedence.

     ( expression )  This evaluates to true if the parenthesized expression evaluates to true.

     ! expression
     -false expression
     -not expression
                     This is the unary NOT operator.  It evaluates to true if the expression is false.

     expression -and expression
     expression expression
                     The -and operator is the logical AND operator.  As it is implied by the juxtaposition of two
                     expressions it does not have to be specified.  The expression evaluates to true if both expres-
                     sions are true.  The second expression is not evaluated if the first expression is false.

     expression -or expression
                     The -or operator is the logical OR operator.  The expression evaluates to true if either the
                     first or the second expression is true.  The second expression is not evaluated if the first
                     expression is true.

     All operands and primaries must be separate arguments to find.  Primaries which themselves take arguments
     expect each argument to be a separate argument to find.
