- it has pull #185 changes - other improvements and - implemented maidenhead grid locator on the C (conky/maidenhead.c) language: - get maidenhead (c implementation) with gpspipe (to get latitude and longitude) gcc is required. see conky/get-grid file. - get maidenhead (c implementation) with passing arguments (passing latitude and longitude as arguments) gcc is required. see conky/get-grid file. - get maidenhead (ruby implementation) fallback to this one if gcc is not installed (different OS maybe). see conky/get-grid.rb file.
