When Guile starts interactively, it notifies the user that help can be
had by typing ‘,help’. Indeed, help is a command, and a
particularly useful one, as it allows the user to discover the rest of
the commands.
all | group | [-c] command]Show help.
With one argument, tries to look up the argument as a group name, giving help on that group if successful. Otherwise tries to look up the argument as a command, giving help on the command.
If there is a command whose name is also a group name, use the ‘-c command’ form to give help on the command instead of the group.
Without any argument, a list of help commands and command groups are displayed.
