  virt-top --csv >(split -d -l 1000 - output.csv.)
 
+RHEL provides a short Python script called C<processcsv.py> which
+can be used to post-process the CSV output.  Run it like this:
+
+ virt-top --csv data.csv
+ processcsv.py < data.csv
+
+This creates or I<overwrites> the following files in the current
+directory:
+
+ global.csv
+ domain<NNN>.csv
+
+C<global.csv> will contain the global data.  One
+C<domainE<lt>NNNE<gt>.csv> file will also be created for each domain
+with ID C<NNN>, containing the per-domain data.
+
 =item B<--no-csv-cpu>
 
 Disable domain CPU stats in CSV output.
