### Simple script to get current Wan IP + Geolocation from Duckduckgo
### v1.4 - adapt to DuckDuck Answer Country only in certain conditions
### v1.3 - removed temp file and awk correction
### v1.2 - Added option to get only Wan IP (-o) and awk output (-a) if specified
### v1.1 - Added colors and myecho functions (available in 'functions' dir in the same repo)

_VERS=$(awk '/### v/ {print $2; exit}' $basename $0)
