+It defines two base elements, @code{TRUE} and @code{FALSE}, and a
+@code{Symbol} class that can take on one of these two values.  Calculations
+are done only in terms of @code{AND}, @code{OR}, and @code{NOT}---other
+compositions like @code{XOR} and @code{NAND} are emulated on top of them.
+Expressions are constructed from parsed strings or directly in Python.")
