The kyuahelp command provides interactive help on all supported commands and options. If, for some
reason, you happen to spot a discrepancy in the output of this command and this document, the command is
the authoritative source of information.
If no arguments are provided, the command prints the list of common options and the list of supported
subcommands.
If the command argument is provided to, this single argument is the name of a valid subcommand. In that
case, kyuahelp prints a textual description of the command, the list of common options and the list of
subcommand-specific options.
