110Objects of this class parse the output of system command-line
111 utilities that can give information about the state of 
112 various hardware components in the system. Typically, each such
113 object either invokes a command and reads its output or reads the
114 output of one such command from a file on the disk. Currently
115 supported utilities include ifconfig, smartmontools, lm-sensors,
116 /proc/cpuinfo.
