+# check\_temp.py #
+Another simple Nagios plugin to check the temperature with lm-sensors.
+This one is written in Python and can be used to monitor any adapter the user
+specifies with the -a option.
+
+## Usage ##
+    usage: check_temp.py [-h] -w N -c N -a string
+
+    optional arguments:
+        -h, --help  show this help message and exit
+        -w N        warning temperature
+        -c N        critical temperature
+        -a string   the adapter to monitor (for example: acpitz-virtual-0)
+
