This is an interesting idea. For boolean knobs, I'd really like to see
us use the NetBSD way:
# checkyesno var
# Test $1 variable, and warn if not set to YES or NO.
# Return 0 if it's "yes" (et al), nonzero otherwise.
#
checkyesno()
{
eval _value=\$${1}
debug "checkyesno: $1 is set to $_value."
case $_value in
# "yes", "true", "on", or "1"
[Yy][Ee][Ss]|[Tt][Rr][Uu][Ee]|[Oo][Nn]|1)
return 0
;;
# "no", "false", "off", or "0"
[Nn][Oo]|[Ff][Aa][Ll][Ss][Ee]|[Oo][Ff][Ff]|0)
return 1
;;
*)
warn "\$${1} is not set properly."
return 1
;;
esac
}
