.SH "OPTIONS"
.PP
\fBPrivoxy\fR may be invoked with the following command line
options:
.TP
-\fB--help\fR
-Print brief usage info and exit.
+\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--version\fR
-Print version info and exit.
+\fB\-\-config-test\fR
+Exit after loading the configuration files before binding to
+the listen address. The exit code signals whether or not the
+configuration files have been successfully loaded.
+
+If the exit code is 1, at least one of the configuration files
+is invalid, if it is 0, all the configuration files have been
+successfully loaded (but may still contain errors that can
+currently only be detected at run time).
+
+This option doesn't affect the log setting, combination with
+"--no-daemon" is recommended if a configured log file shouldn't
+be used.
.TP
-\fB--no-daemon\fR
+\fB\-\-help\fR
+Print brief usage info and exit.
+.TP
+\fB\-\-no-daemon\fR
Don't become a daemon, i.e. don't fork and become process group
leader, don't detach from controlling tty, and do all logging there.
.TP
-\fB--pidfile \fIpidfile\fB\fR
+\fB\-\-pidfile \fIpidfile\fB\fR
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.
+is non-fatal. If no \fB\-\-pidfile\fR option is given, no PID file will be used.
+.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.
.TP
-\fB--user \fIuser[.group]\fB\fR
+\fB\-\-user \fIuser[.group]\fB\fR
After (optionally) writing the PID file, assume the user ID of
\fIuser\fR and the GID of
\fIgroup\fR, or, if the optional
\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.
+\fB\-\-version\fR
+Print version info and exit.
.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
+\fIconfig\fR in the current directory. If no
+\fIconfigfile\fR is found, \fBPrivoxy\fR will
fail to start.

-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

\fBPrivoxy\fR can be configured with the various configuration
files. The default configuration files are: \fIconfig\fR,
-\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
-\fBPrivoxy\fR uses the concept of \fBactions\fR
+\fIdefault.filter\fR, \fIdefault.action\fR and
