< မေႃႇၵျူး:Country alias
-- This module returns the country name or the flag name for a country,
-- based on the three-letter IOC/CGA/FINA alias.

--[[
The following country code is used for multiple countries:
    ANG (workaround: added ANG_CGF for use with Commonwealth Games)

The following names have different names/flags based on sport/year
    Great Britain (and N.I.)         GBR, GBR_WCA (latter added to add text in parens)
    Hong Kong                        HKG, HKG_CGF (latter added to keep colonial flag)
    Individual Olympic Athletes      IOA, IOA_2000 (IOA changed to Independent Olympic Athletes in 2012)
    Russian Athletes				 OAR (2018), ROC_2020 (2020 Summer, 2022 Winter)
    SWZ                              Swaziland became Eswatini after the 2018 Commonwealth Games
    MKD								 Macedonia became North Macedonia in 2019
    ART								 No "Athlete" before Refugee Team @ 2017 AIMAG
    D.R. of the Congo				 Was Zaire (ZAI) and Congo-Kinshasa (COK_COD)
