Example of your Unique Scrypt Run Commands:
cgminer.exe --scrypt -o stratum+tcp://scrypt.eobot.com:4444 --userpass eobot.29761:x
minerd.exe -a scrypt -o stratum+tcp://scrypt.eobot.com:4444 --userpass eobot.29761:x

Important to Increase Scrypt Speed:
The default cgminer settings does not include hardware specific flags, which you may find here in the Litecoin Mining Hardware Comparison. Failing to use the proper flags can result in performance decreases in excess of 50%.
