/* Theory of operation
 *
 * DCMI is the Data Center Management Interface which is a subset of IPMI v2.0.
 * DCMI incorporates the ability to locate a system with DCMI functionality,
 * its available temperature sensors, and power limiting control.
 *
 * All of the available DCMI commands are contained in a struct with a numeric
 * value and a string.  When the user specifies a command the string is
 * compared to one of several structs and is then given a numeric value based
 * on the matched string.  A case statement is used to select the desired
 * action from the user.  If an invalid string is entered, or a string that is
 * not a command option is entered, the available commands are printed to the
 * screen.  This allows the strings to be changed quickly with the DCMI spec.
 *
 * Each called function usually executes whichever command was requested to
 * keep the main() from being overly complicated.
 *
 * This code conforms to the 1.0 DCMI Specification
 *  released by Hari Ramachandran of the Intel Corporation
