+<para>
+ <application>Privoxy</application> processes all the raw content of every
+ web page. So it reads everything on each page. It then compares this to the
+ rules as set up in the configuration files, and looks for any matches to
+ these rules. <application>Privoxy</application> makes heavy use of
+ <quote>regular expressions</quote>. (If you are not familiar with regular
+ expressions, it is explained briefly in <ulink
+ url="../user-manual/appendix.html">the user manual</ulink>.) Regular
+ expressions facilitate matching of one text string against another, using
+ wildcards to build complex patterns. So <application>Privoxy</application>
+ will typically look for URLs and other content that match certain key words
+ and expressions as defined in the configuration files. For instance a URL
+ that contains <quote>/banners</quote>, has a high probability of containing
+ ad banners, and thus would be a prime candidate to have a matching rule.
+</para>
+<para>
+ So <application>Privoxy</application> will look for these kinds of obvious
+ looking culprits. And also, will use lists of known organizations that
