Yep, being so specific I hadn't considered setting it any where other
than mk.conf. So it's more of a precaution then :)
But, the options that are used are not the value of PKG_OPTIONS.cups,

Perhaps the last line should say
You can add or remove options by setting PKG_DEFAULT_OPTIONS or
PKG_OPTIONS.cups to include, e.g., +option1 or -option2.
