   4#   Analyse Apache (httpd) server logs, including data transferred, requests,
   5#   clients, and errors. Note that Apache's logs can get filled up very quickly
   6#   with the default verbosity, leading to logparse taking a very long time to
   7#   analyse them. In general the default verbosity is good, but logs should be
   8#   cleared as soon as they are analysed (make sure 'rotate' is set to 'y').
