2.1. Processes

ECL provides several facilities for invoking and communicating with ext:external-process. If one just wishes to execute some program, without caring for its output, then probably ext:system is the best function. In all other cases it is preferable to use ext:run-program, which opens pipes to communicate with the program and manipulate it while it runs on the background.
