         ||             11            logical or

Operator priority can be ignored by using parentheses, for example (1 + 1) * 2
equals 4, while 1 + 1 * 2 equals 3.

         ------------------------------------------------
         >               4            alphabetical greater than
         >=              4            alphabetical greater than or equal
         <               4            alphabetical less than
         <=              4            alphabetical less than or equal
         ==              5            alphabetical equal (can use regex)
         !=              5            alphabetical not equal (can use regex)

Strings must be encased in double quotes or braces. The > >= < <= operators
perform basic string comparisons. The == != operators perform regular
expressions, with the argument on the left being the string, and the argument
on the right being the regex. For example {bla} == {%*a} would evaluate as 1.
