+
+.SH SYNOPSIS
+.B @@PACKAGE@@
+[\fIOPTION\fR] [\fIPATH\fR|\fIURL\fR]
+
+.SH DESCRIPTION
+See the Brave Help Center for help on using the browser.
+.IP
+<https://support.brave.com/>
+.PP
+This manpage only describes invocation, environment, and arguments.
+
+.SH OPTIONS
+@@MENUNAME@@ has hundreds of undocumented command-line flags that are added
+and removed at the whim of the developers.  Here, we document relatively
+stable flags.
+.TP
+\fB\-\-user\-data\-dir\fR=\fIDIR\fR
+Specifies the directory that user data (your "profile") is kept in.
+Defaults to
+.I $HOME/.config/@@PACKAGE@@ .
+Separate instances of @@MENUNAME@@ must use separate user data directories;
+repeated invocations of @@PACKAGE@@ will reuse an existing process for
+a given user data directory.
+
+.TP
+\fB\-\-app\fR=\fIURL\fR
+Runs
+.I URL
+in "app mode": with no browser toolbars.
+
+.TP
+\fB\-\-incognito\fR
+Open in incognito mode.
+
+.TP
+\fB\-\-new-window\fR
+If \fIPATH\fR or \fIURL\fR is given, open it in a new window.
+
+.TP
+\fB\-\-proxy-server\fR=\fIhost:port\fR
+Specify the HTTP/SOCKS4/SOCKS5 proxy server to use for requests.  This
+overrides any environment variables or settings picked via the options dialog.
+An individual proxy server is specified using the format:
+
+  [<proxy-scheme>://]<proxy-host>[:<proxy-port>]
+
+Where <proxy-scheme> is the protocol of the proxy server, and is one of:
+
+  "http", "socks", "socks4", "socks5".
+
+If the <proxy-scheme> is omitted, it defaults to "http". Also note that
+"socks" is equivalent to "socks5".
+
+Examples:
+
+  --proxy-server="foopy:99"
+      Use the HTTP proxy "foopy:99" to load all URLs.
+
+  --proxy-server="socks://foobar:1080"
+      Use the SOCKS v5 proxy "foobar:1080" to load all URLs.
+
+  --proxy-server="socks4://foobar:1080"
+      Use the SOCKS v4 proxy "foobar:1080" to load all URLs.
+
+  --proxy-server="socks5://foobar:66"
+      Use the SOCKS v5 proxy "foobar:66" to load all URLs.
+
+It is also possible to specify a separate proxy server for different URL types,
+by prefixing the proxy server specifier with a URL specifier:
+
+Example:
+
+  --proxy-server="https=proxy1:80;http=socks4://baz:1080"
+      Load https://* URLs using the HTTP proxy "proxy1:80". And load http://*
+      URLs using the SOCKS v4 proxy "baz:1080".
+
+.TP
+\fB\-\-no-proxy-server\fR
+Disables the proxy server.  Overrides any environment variables or
+settings picked via the options dialog.
+
+.TP
+\fB\-\-proxy-auto-detect\fR
+Autodetect proxy configuration.  Overrides any environment variables
+or settings picked via the options dialog.
+
+.TP
+\fB\-\-proxy-pac-url\fR=\fIURL\fR
+Specify proxy autoconfiguration URL.  Overrides any environment variables
+or settings picked via the options dialog.
+
+.TP
+\fB\-\-password-store\fR=<\fIbasic\fR|\fIgnome\fR|\fIkwallet\fR>
+Set the password store to use.  The default is to automatically detect based
+on the desktop environment.  \fIbasic\fR selects the built in, unencrypted
+password store.  \fIgnome\fR selects Gnome keyring.  \fIkwallet\fR selects
+(KDE) KWallet.  (Note that KWallet may not work reliably outside KDE.)
+
+.TP
+\fB\-\-version\fR
+Show version information.
+
+.PP
+As a GTK+ app, @@MENUNAME@@ also obeys GTK+ command-line flags, such
+as
+.BR \-\-display .
+See the GTK documentation for more:
+.IP
+<http://library.gnome.org/devel/gtk/stable/gtk-running.html>
+<http://library.gnome.org/devel/gtk/stable/gtk-x11.html>
+
+.SH ENVIRONMENT
+@@MENUNAME@@ obeys the following environment variables:
+
+.TP
+.B all_proxy
+Shorthand for specifying all of
+.B http_proxy, https_proxy, ftp_proxy
+
+.TP
+.B http_proxy, https_proxy, ftp_proxy
+The proxy servers used for HTTP, HTTPS, and FTP.
+.I Note:
+because Gnome/KDE proxy settings may propagate into these variables
+in some terminals, this variable is ignored (in preference for actual
+system proxy settings) when running under Gnome or KDE.  Use the
+command-line flags to set these when you want to force their values.
+
+.TP
+.B auto_proxy
+Specify proxy autoconfiguration.  Defined and empty autodetects; otherwise,
+it should be an autoconfig URL.  But see above note about Gnome/KDE.
+
+.TP
+.B SOCKS_SERVER
+SOCKS proxy server (defaults to SOCKS v4, also set
+.B SOCKS_VERSION=5
+to use SOCKS v5).
+
+.TP
+.B no_proxy
+Comma separated list of hosts or patterns to bypass proxying.
+
+.SH FILES
+.TP
+.I $HOME/.config/@@PACKAGE@@
+Default directory for configuration data.
+
+.TP
+.I $HOME/.cache/@@PACKAGE@@
+Default directory for cache data.  (Why?  See
+<http://standards.freedesktop.org/basedir-spec/latest/> .)
