-The following options may be specified on the command line:
-"-c configfile" to specify a non-default config file path.
-"-d loglevel" to set a loglevel of 1, 2, 3, 4 and 5 where 5 is the
-              most detailed.
-"-f" to run the proxy in the foreground with logging to stderr.
-     Without "-f" the default is to detach as a daemon and log to
-     syslog.
-"-i pidfile" to name a file to which the PID is written.
-"-v" just prints version information and exits.
-"-p" (pretend) makes the proxy go through the configuration files as
-     normal, but stops before creating any sockets or doing any
-     serious work.  This is useful for validating config files.
+Note for Cygwin users:
+Due to a bug in openssl the tls option CACertificatePath is currently unusable.
+Use a certificate bundle with CACertificateFile instead.
