yes please. There would be no harm in including it in the pcp distro. As with
your previous contributions, you need to give it to SGI before I can include
it in the distribution.

pmlogger_daily and/or pmlogger_merge should be enough to merge the daily
logs .. but knowing you, your own script was necessary ;-)
