leader, don't detach from controlling tty, and do all logging there.
.TP
\fB--pidfile \fIpidfile\fB\fR
-After (optionally) writing the PID file, assume the user ID of user
-and the GID of group, or, if the optional group was not given, the
-default group of user. Exit if the privileges are not sufficient to
-do so.
+On startup, write the process ID to \fIpidfile\fR.
+Delete the \fIpidfile\fR on exit.
+Failure to create or delete the \fIpidfile\fR
+is non-fatal. If no \fB--pidfile\fR option is given, no PID file will be used.
.TP
\fB--user \fIuser[.group]\fB\fR
After (optionally) writing the PID file, assume the user ID of
\fIgroup\fR was not given, the default group of
\fIuser\fR. Exit if the privileges are not
sufficient to do so.
+.TP
+\fB--chroot\fR
+Before changing to the user ID given in the --user option, chroot to
+that user's home directory, i.e. make the kernel pretend to the
+\fBPrivoxy\fR process that the directory tree starts
+there. If set up carefully, this can limit the impact of possible
+vulnerabilities in \fBPrivoxy\fR to the files contained in
+that hierarchy.
+.TP
+\fB--pre-chroot-nslookup \fIhostname\fB\fR
+Initialize the resolver library using \fIhostname\fR
+before chroot'ing. On some systems this reduces the number of files
+that must be copied into the chroot tree.
.PP
If the \fIconfigfile\fR is not specified on the command line,
\fBPrivoxy\fR will look for a file named
-\fIconfig\fR in the current directory (except on Win32 where
-it will try \fIconfig.txt\fR). If no
+\fIconfig\fR in the current directory . If no
\fIconfigfile\fR is found, \fBPrivoxy\fR will
fail to start.
.SH "DESCRIPTION"
.PP
-\fBPrivoxy\fR is a web proxy with advanced filtering
-capabilities for protecting privacy, filtering web page content, managing
-cookies, controlling access, and removing ads, banners, pop-ups and other
-obnoxious Internet junk. \fBPrivoxy\fR has a very
-flexible configuration and can be customized to suit individual needs and
-tastes. \fBPrivoxy\fR has application for both
-stand-alone systems and multi-user networks.
+Privoxy is a non-caching
+web proxy
+with advanced filtering capabilities for enhancing privacy,
+modifying web page data, managing HTTP
+cookies,
+controlling access, and removing ads, banners, pop-ups and other obnoxious
+Internet junk. Privoxy has a flexible configuration and can be
+customized to suit individual needs and tastes. Privoxy has application for
+both stand-alone systems and multi-user networks.
.PP
-\fBPrivoxy\fR is based on the code of the
-\fBInternet Junkbuster\fR (tm).
-\fBJunkbuster\fR was originally written by Junkbusters
-Corporation, and was released as free open-source software under the GNU GPL.
-Stefan Waldherr made many improvements, and started the SourceForge project
-to continue development.
-.PP
-\fBPrivoxy\fR continues the
-\fBJunkbuster\fR tradition, but adds many
-refinements, enhancements and new features.
+Privoxy is based on Internet Junkbuster (tm).
.SH "INSTALLATION AND USAGE"
.PP
-Browsers must be individually configured to use \fBPrivoxy\fR as
-a HTTP proxy. The default setting is for localhost, on port 8118
-(configurable in the main config file). To set the HTTP proxy in Netscape
-and Mozilla, go through: \fBEdit\fR;
+Browsers can either be individually configured to use
+\fBPrivoxy\fR as a HTTP proxy (recommended),
+or \fBPrivoxy\fR can be combined with a packet
+filter to build an intercepting proxy
+(see \fIconfig\fR). The default setting is for
+localhost, on port 8118 (configurable in the main config file). To set the
+HTTP proxy in Netscape and Mozilla, go through: \fBEdit\fR;
\fBPreferences\fR; \fBAdvanced\fR;
\fBProxies\fR; \fBManual Proxy Configuration\fR;
\fBView\fR.
.PP
+For Firefox, go through: \fBTools\fR;
+\fBOptions\fR; \fBGeneral\fR;
+\fBConnection Settings\fR;
+\fBManual Proxy Configuration\fR.
+.PP
For Internet Explorer, go through: \fBTools\fR;
\fBInternet Properties\fR; \fBConnections\fR;
\fBLAN Settings\fR.
.PP
The Secure (SSL) Proxy should also be set to the same values, otherwise
-https: URLs will not be proxied.
+https: URLs will not be proxied. Note: \fBPrivoxy\fR can only
+proxy HTTP and HTTPS traffic. Do not try it with FTP or other protocols.
+HTTPS presents some limitations, and not all features will work with HTTPS
+connections.
.PP
For other browsers, check the documentation.
.SH "CONFIGURATION"
.PP
\fBPrivoxy\fR can be configured with the various configuration
files. The default configuration files are: \fIconfig\fR,
-\fIdefault.action\fR, and
-\fIdefault.filter\fR. These are well commented. On Unix and
-Unix-like systems, these are located in \fI/etc/privoxy/\fR by
-default. On Windows, OS/2 and AmigaOS, these files are in the same directory
-as the \fBPrivoxy\fR executable.
+\fIdefault.filter\fR, and
+\fIdefault.action\fR. \fIuser.action\fR should
+be used for locally defined exceptions to the default rules of
+\fIdefault.action\fR, and \fIuser.filter\fR for
+locally defined filters. These are well commented. On Unix
+and Unix-like systems, these are located in
+\fI/etc/privoxy/\fR by default.
.PP
-The name and number of configuration files has changed from previous
-versions, and is subject to change as development progresses. In fact, the
-configuration itself is changed and much more sophisticated. See the
-user-manual for a
-brief explanation of all configuration options.
+\fBPrivoxy\fR uses the concept of \fBactions\fR
+in order to manipulate the data stream between the browser and remote sites.
+There are various actions available with specific functions for such things
+as blocking web sites, managing cookies, etc. These actions can be invoked
+individually or combined, and used against individual URLs, or groups of URLs
+that can be defined using wildcards and regular expressions. The result is
+that the user has greatly enhanced control and freedom.
.PP
The actions list (ad blocks, etc) can also be configured with your
-web browser at http://ijbswa.sourceforge.net/config.
+web browser at http://config.privoxy.org/
+(assuming the configuration allows it).
\fBPrivoxy's\fR configuration parameters can also be viewed at
the same page. In addition, \fBPrivoxy\fR can be toggled on/off.
-This is an internal page.
+This is an internal page, and does not require Internet access.
+.PP
+See the \fIUser Manual\fR for a detailed
+explanation of installation, general usage, all configuration options, new
+features and notes on upgrading.
