boolean expression evaluator - source code?

[Anonymous]

Hi;

Does anyone know of any available source code that will do boolean
expression evaluations?

All I need is something that can evaluate things like:
(3 > 4) || true

I already have the variables substituted so it's just the final
expression I need to evaluate.

thanks - dave
