+Configuring the Go Application
+=======================
+Traffic Ops is in the process of migrating from Perl to Go, and currently
runs as two applications. The Go application serves all endpoints which have
been rewritten in the Go language, and transparently proxies all other requests
to the old Perl application. Both applications are installed by the RPM, and
both run as a single service. When the project has fully migrated to Go, the
Perl application will be removed, and the RPM and service will consist solely
of the Go application.
-
+By default, the postinstall script configures the Go application to behave
and transparently serve as the old Perl Traffic Ops did in previous versions.
This includes reading the old ``cdn.conf`` and ``database.conf`` config files,
and logging to the old ``access.log`` location. However, if you wish to
customize the Go Traffic Ops application, you can do so by running it with the
``-oldcfg=false`` argument. By default, it will then look for a config file in
``/opt/traffic_ops/conf/traffic_ops_golang.json``. The new config file location
may also be customized via the ``-cfg`` flag. A sample config file is installed
by the RPM at ``/opt/traffic_ops/conf/traffic_ops_golang.json``. If you wish to
run the new Go Traffic Ops application as a service with a new config file, the
``-oldcfg=false`` and ``-cfg`` flags may be added to the ``start`` function in
the service file, located by default at ``etc/init.d/traffic_ops``.

Should this `/opt/traffic_ops/conf/traffic_ops_golang.json` be
`/opt/traffic_ops/conf/traffic_ops_golang.config`?
