+Module for displaying NVIDIA GPU temperature
+
+Requires:
+    - nvidia-smi
+
+Configuration parameters:
+    - cache_timeout: how often we refresh this module in seconds
+    - color_good: the color used if everything is OK. 
+    - color_bad: the color used if the temperature can't be read.
+    - format_prefix: a prefix for the output.
+    - format_units: the temperature units. Will appear at the end.
+    - separator: the separator char between temperatures (only if more than one GPU)
