<<-DESCRIPTION
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.
