+- generate a LaTeX truth table from a statement
+
+### [Logic/Statements/Laws.hs](Logic/Statements/Laws.hs)
 
-- evaluate statements
-- from a statement generate a LaTeX truth table
 - match/replace patterns in statements (e.g. logical laws)
 - verify logical-law equivalence of statements (TODO)
-- find logical-law equivalence of statements with breadth-first search
+- find logical-law equivalence of statements with breadth-first search (slow)
