# In order to work with QtLockscreen I need to, in the WORST case scenario:
# http://weather.yahoo.com/weather.yahooapis.com/forecastrss?w=455861&u=c?unit=c
# 1) Remove the 'http://weather.yahoo.com/'
# 2) Translate the appended '?unit=X' to '&u=X'
url=`echo "$url" | sed s/weather.yahoo.com\\\/// | sed 's/&u=[cf]//' | sed 's/?unit/\&u/'`
# the only problem is that now it requires the ?unit=c to recognize celcius, but for the qtlockscreen it is ok.
