<refsect1><title>Description</title>
<para>
<command>sarg</command> is a log file parser and analyzer for the <ulink url="http://www.squid-cache.org/">Squid Web Proxy Cache</ulink>.
It allows you to view "where" your users are going to on
the Internet.
</para>
<para>
<command>sarg</command> generates reports in HTML with fields such as: users,
IP Addresses, bytes, sites, and times. These HTML files can appear in your
web server's directory for browsing by users or administrators. You may also
have <command>sarg</command> email the reports to the Squid Cache administrator.
</para>
<para>
<command>sarg</command> can read <application>squid</application> or <application>Microsoft ISA</application> access logs.
Optionally, it can complement the reports with the log of a Squid filter/redirector such as
<ulink url="http://www.squidguard.org/">squidGuard</ulink>.
</para>
