Usage: wttr [-s] [-d] [-u] [-i] [-f] [-h]

Queries the weather and outputs it in a Nerd Font compaitable way

Options:
  -s, --setloc=<LOC>    change location used for wttr.in query
                          clears disploc on set
  -d, --disploc=<LOC>   set a location name to display instead of the 
                          location used in wttr.in query
  -u, --unit={c|f}      set the output unit to fahrenheit or celsius
  -i, --info            shows current values of location, unit and
                          disploc if it is set
  -f, --force           force refresh weather data
  -h, --help            Show this help message
