I have always been irritated by the fact that the help text cannot be piped. Neither a
falcon-main --help |less(the help is meanwhile 79 lines long) will work nor afalcon-main --help |grep -A3 penal(which should e.g. provide a compilation in a few lines with everything that has to do with penalties commands).That is because the help output is written to
stderr. But a help text output with--helpis not an error message, but the desired text output of the help command.This pr changes the output going to
stdout, making possible to pipe the textand allow processing with grep, less, etc.
