Being a total Perl noob I get tasked with some log parsing duties. The
project involves parsing the apache access log. What I need to be able
to do is get the "time served" data per hour per page.

Something like: script.pl <url> <time> would return all the logged
instances of that url and how long it took to serve each page for the
time requested. I was able to pull that data out using awk into a flat
file, however that's not as efficient as having Perl read thru the file
and store the data on the fly.. I just have no idea how to start.. does
anyone have any ideas on this?
