  <<-EOD
    set <setting> <value>

    #{short_description}

    Boolean values take "on", "off", "true", "false", "1" or "0". If you
    don't specify a value, the boolean setting will be enabled. Conversely,
    you can use "set no<setting>" to disable them.

    You can see these environment settings with the "show" command.
