"To qualify for the subscription prices, purchasers will have to provide evidence that they have purchased a full copy of Castle's C/C++ development tools, within the last three years, when registering online for upgrades."

I am trapped on a roof ... with an unstable human who drinks too much whiskey and who called me a smurf.
