Do you get bored of playing engines for benchmarks or some tasks from command lines: start a terminal/console, go to engine folder, enter the runnable file name, add parameters, run it… All are text and typing, no mouse. If you have to guide someone who has never run a program via a terminal/console before, it may become a nightmare!
BSG can help to solve that problem. Just open the Benchmark/cmd dialog (menu -> Tools -> Benchmark/cmd), select an engine and click on the run button. If you need to run frequently an engine with specific parameters, just edit the field Parameters and all will be remembered.
