[Boatanchors] "L" network problem solver?

[Sandy]

Somewhere on the web I found a program that you feed in the vector impedance 
of an antenna ( say 123-j58 ohms) and it will give you the values of an "L" 
network to match this to a 50 ohm transmitter.

Anybody recall where one of these "calculators" is on the internet?

I had one on my former computer but the datat was lost when a big lightning 
bolt took out the machine!
