+OpenVPN fwmark Routing
+Sean Reifschneider, <jafo@tummy.com>
+Thursday November 27, 2003
+==========================
+
+These scripts can be used with OpenVPN up and down scripts to set up
+routing on a Linux system such that the VPN traffic is sent via normal
+network connectivity, but other traffic to that network runs over the VPN.
+The idea is to allow encryption of data to the network the remote host is
+on, without interfering with the VPN traffic.  You can't simply add a route
+to the remote network, becaues that will cause the VPN traffic to also try
+to run over the VPN, and breaks the VPN.
+
+These scripts use the Linux "fwmark" iptables rules to specify routing
+based not only on IP address, but also by port and protocol.  This allows
+you to effectively say "if the packet is to this IP address on this port
+using this protocol, then use the normal default gateway, otherwise use the
+VPN gateway.
+
+This is set up on the client VPN system, not the VPN server.  These scripts
+also set up all ICMP echo-responses to run across the VPN.  You can
+comment the lines in the scripts to disable this, but I find this useful
+at coffee shops which have networks that block ICMP.
+
+To configure this, you need to set up these scripts as your up and down
+scripts in the config file.  You will need to set these values in the
+config file:
+
+   up /etc/openvpn/fwmarkroute.up
+   down /etc/openvpn/fwmarkroute.down
+   up-restart
+   up-delay
+
+   setenv remote_netmask_bits 24
+
+Note: For this to work, you can't set the "user" or "group" config options,
+because then the scripts will not run as root.
+
+The last setting allows you to control the size of the network the remote
+system is on.  The remote end has to be set up to route, probably with
+masquerading or NAT.  The network this netmask relates to is calculated
+using the value of "remote" in the conf file.
+

-OpenVPN fwmark Routing
-Sean Reifschneider, <jafo@tummy.com>
-Thursday November 27, 2003
-==========================
-
-These scripts can be used with OpenVPN up and down scripts to set up
-routing on a Linux system such that the VPN traffic is sent via normal
-network connectivity, but other traffic to that network runs over the VPN.
-The idea is to allow encryption of data to the network the remote host is
-on, without interfering with the VPN traffic.  You can't simply add a route
-to the remote network, becaues that will cause the VPN traffic to also try
-to run over the VPN, and breaks the VPN.
-
-These scripts use the Linux "fwmark" iptables rules to specify routing
-based not only on IP address, but also by port and protocol.  This allows
-you to effectively say "if the packet is to this IP address on this port
-using this protocol, then use the normal default gateway, otherwise use the
-VPN gateway.
-
-This is set up on the client VPN system, not the VPN server.  These scripts
-also set up all ICMP echo-responses to run across the VPN.  You can
-comment the lines in the scripts to disable this, but I find this useful
-at coffee shops which have networks that block ICMP.
-
-To configure this, you need to set up these scripts as your up and down
-scripts in the config file.  You will need to set these values in the
-config file:
-
-   up /etc/openvpn/fwmarkroute.up
-   down /etc/openvpn/fwmarkroute.down
-   up-restart
-   up-delay
-
-   setenv remote_netmask_bits 24
-
-Note: For this to work, you can't set the "user" or "group" config options,
-because then the scripts will not run as root.
-
-The last setting allows you to control the size of the network the remote
-system is on.  The remote end has to be set up to route, probably with
-masquerading or NAT.  The network this netmask relates to is calculated
-using the value of "remote" in the conf file.

Subject: Back to the standard "app" module.

This return to "app" instead of "bitmask_android" is due to this reading: https://developer.android.com/sdk/installing/studio-build.html#projectStructure
I'll have to tweak the final apk name in build.gradle.

+# will require the use of the OpenVPN "down-root" plugin
