  4.     # Name                  m00nie::weather
  5.     # Description           Uses wunderground API to grab some weather...
  6.     # Version               1.6 - Corrects wind conditions when set to Metric, or Combined
  7.     #                             Adjusted styling for better readability

  9.     #                             both F and C temps in the same output. Might add this to forecast in future version
  10.     #                       1.4 - Warn on more than 5 possible restults (stops LOTS of spam)
  11.     #                       1.3 - Added warning when mutlple/unclear matches
