 .SH TOO MUCH INFORMATION EXAMPLE
 By default, turbostat dumps all possible information -- a system configuration header, followed by columns for all counters.
 This is ideal for remote debugging, use the "--out" option to save everything to a text file, and get that file to the expert helping you debug.
