The finite-difference engines provide delta and gamma. For the other  
Greeks, you can either take the Barone-Adesi-Whaley and/or the  
Bjerksund-Stensland engine, differentiate the analytic formulas they  
implement, and add the corresponding greeks (in which case I'd be  
grateful for a patch) or take any engine and calculate the Greeks  
numerically (calculate, change an input slightly, recalculate, take the  
difference.)

Later,
