Buy a lot of Jolt and be prepared to work long hours. Your other alternative is to write a Perl parser to check for all occurances of 'and' and 'or' in an expression.

You could speed up the process using grep (the *nix command, not the builtin) to search for all occurances of 'and' and 'or' in your code and print the line numbers.
