-\fB --user\fP \fIuser\fP[.\fIgroup\fP] (unix only)
-After (optionally) writing the PID file, assume the user ID
-of \fIuser\fP and the GID of \fIgroup\fP, or, if the optional
-\fIgroup\fP was not given, the default group of \fIuser\fP.
-Exit if the privileges are not sufficient to do so.

+\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.
+.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 . If no
+\fIconfigfile\fR is found, \fBPrivoxy\fR will
+fail to start.
+.SH "DESCRIPTION"
+.PP
+Privoxy is a
+web proxy
+with advanced filtering capabilities for protecting
+privacy, modifying web page data, managing
+cookies,
+controlling access, and removing ads, banners, pop-ups and other obnoxious
+Internet junk. Privoxy has a very 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
+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;
+\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. 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.
