* !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
* IMPORTANT NOTE ABOUT ADDING A NEW VALUE FOR REPORTING
* !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
*
* When adding a new string value to report, try to keep it
* self-descriptive so when it's printed even without the header,
* we can still deduce what it is actually reporting.
*
* If you need more than one descriptive string to mean the same value,
* please define them as reserved values in values.h.
*
* The first reserved value is the one that is printed in reports (unless
* it's a binary value and we have report/binary_values_as_numeric=1 config
* option used OR --binary command line option is used OR we're using an
* output format which must always print binary values in numeric way,
* like json_std output format.
*
* All the other (2nd and further) listed reserved names are synonyms which
* may be also used in selection (-S|--select).
*
* Also, always use proper *_disp functions to display each type of value
* properly. For example, in case of binary values, you should use
* _binary_disp so that we can always switch between numerical (0/1/-1) and
* string representation while reporting the value.
