Module: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) SWZ                             (Swaziland became Eswatini after the 2018 Commonwealth Games)

The following names occur twice due to CGF/IOC/FINA/IAAF/etc differences Anguilla                        AIA, ANG_CGF Antigua and Barbuda             ANT, ATG Bahrain                         BHN, BHR, BRN Curaçao                         CUR, CUW Faroe Islands                   FAR, FRO Guernsey                        GGY, GUE Iran                            IRI, IRN Ireland                         IRE, IRL - IRE is *only* for CGF apps Jersey                          JER, JEY Lebanon                         LBN, LIB Montserrat                      MNT, MSR Nicaragua                       NCA, NIC Norfolk Island                  NFI, NFK Oman                            OMA, OMN Refugee Olympic Team            ROA, ROT Romania                         ROM, ROU Saint Helena                    SHE, SHN Saint Vincent and the Grenadines SVG, VIN Sarawak                         SAR, SWK Singapore                       SGP, SIN South Africa                    RSA, SAF Tonga                           TGA, TON Trinidad and Tobago             TRI, TTO Turks and Caicos Islands        TCA, TCI, TKS
