In certain cases, you may find it more useful to report full column names
instead of abbreviated column names in report headings. To do this, use
\fBreport/headings=2\fP configuration setting (or \fB--headings full\fP
or \fB--headings 2\fP command line option). The full column names are
the exact names that you also use in \fIFieldSet\fP for \fB-o|--options\fP.
These names are unambiguous, without spaces (one word only) and they also
make it easier to match the output with requested \fIFieldSet\fP:
