into a summary file
which contains a count of the
number of times each command was called and the time resources consumed.
This condensation is desirable because on a large system
can grow by 500K bytes per day.
The summary file is normally read before the accounting file,
so the reports include all available information.
If a file name is given as the last argument, that file will be treated
as the accounting file;

Output fields are labeled:

averaged core usage (in 1k units),
for average number of
operations per execution.
