(The current list is "true", "yes", "on", and "enabled" evaluate to 1,
"false", "no", "off", and "disabled" to 0, anything else is passed
through strtol.  This is specifically a configuration system, where it
makes sense to be forgiving in what you accept, but you did ask for a
language *or system*.)
