##"en" and "en-us" versions of a page.
My site is in non-US English. However, I want US-English people to find my site when they search for it when they use US spelling on certain search terms (such as "optimise" versus "optimize"). This requires a (crude) US-English version of the site where the spellings are changed automatically, and the LANG is "en-us" rather than "en". (No, don't tell me to use keywords; Google ignores keywords and has for a number of years).
