This class is intended to be used to clean up directories which accumulate
files during SkyView operations. E.g., we might have java -cp
skyview.jar:fits.jar skyview.ops.DirScan /web_chroot/cache/results/fits
time=36000 largetime=60 large=10 recordFile="/data/logs/account/querystats"
email="firstname.lastname@example.org" mailCmd="./mailSender.pl" debug=true
This cleans up all files after a specified time and files larger than after a
specified number of MBs and after a possibly different specified amount of
time. It appends information from SkyView FITS files files in a log file and
sends an E-mail (using the specified Perl script) to a skyview user. It might
be run hourly using a cron job.
