# This part is taken from the original plugin

|
# Example usage:
|
|
# Do
|
|
# ln -s /path/to/openweather_ openweather_<type>_<id>
|
|
# where <type> is currently ignored (formerly one of
|
|
# [station, weather]) and <id> is a suitable
|
|
# city id from http://openweathermap.org/
|
|
# These parameters translate directly into a URL formed like this:
|
|
# http://openweathermap.org/data/<api>/weather?id=<id>
|
|
#
|
|
# Example config:
|
|
# [openweather_*]
