    * dmidecode2array.php

    * 

    * Set of routines which convert the output of dmidecode into an array containing key/value pairs.

    *

    * Use this by including the file in your script, load the output of a dmidecode run into an array of lines, then call

    * $array = dmidecode2array( $contentsOfFile ).

    * Sample code to read a file name from ARGV, process the file and dump the resulting array using print_r shown at

    * bottom of this file, commented out.
