+
+# Revision .6 2004/01/20 13:47:28 jlaska
+# - modified screen drawing to support different resolutions and OSD_OVERSCAN
values
+# - added support to retry radar map and data downloads on http
timeouts/errors
+# - rolled the date calculations back to python2.2 time module (no longer
datetime)
+#
+# Revision .7 2004/01/20 13:47:28 jlaska
+# - bug in my date math for calculating the day name (oops)
+#
+# Revision .8 2004/02/28 09:19:43 jlaska
+# - double check visibility string is not empty when passing to float()
+# - increased console error verbosity when attempting to parse weather data
+# - added MENU_SELECT handler for weather detail screen to update forecast
data on demand
+# - added ability to specify custom name in PLUGIN_WEATHER_LOCATIONS
