This provides help messages for the futility commands similar to the way git does. These show the available commands: futility futility help futility --help While these show help for a specific command: futility help COMMAND futility --help COMMAND futility COMMAND --help BUG=none BRANCH=ToT TEST=manual make runtests And manually look at help messages for each command.
