From 092ae90eab1d71726d3baf4021cc375b2773d1b7 Mon Sep 17 00:00:00 2001
From: Reid Spencer <rspencer@reidspencer.com>
Date: Fri, 11 Aug 2006 18:36:55 +0000
Subject: [PATCH] Drop the -details option, it was broken. If you want to know
 about a particular directory, just pass that directory to the script. Also,
 clean up the HTML output, put list of skipped dirs at the end, and make a few
 other minor improvements.
