 13 \fBthermometer \fP captures the thermal zones     
 14 specified sampling period. It is optimized to     
 15 possible the overhead while doing the temperat    
 16 to prevent disrupting the running application     
 17                                                   
 18 This low overhead also allows a high rate samp    
 19 which could be necessary to spot overshots and    
 20                                                   
 21 If no configuration file is specified, then al    
 22 be monitored at 4Hz, so every 250ms. A configu    
 23 the thermal zone names and the desired samplin    
 24 name can be a regular expression to specify a     
 25                                                   
 26 The sampling of the different thermal zones wi    
 27 separate files with the thermal zone name. It     
 28 postfix to identify them for example for a spe    
 29 output directory can be specified in addition.    
 30

 32 zone temperatures every 250ms and write to the    
 33 captured files postfixed with the current date

 36 capture ends at the end of the duration if the
