Comments:       ExaBGP, Python BGP route injector
                ExaBGP provides a convenient way to implement
                Software Defined Networking by transforming BGP
                messages into friendly plain text or JSON, which can
                then be easily handled by simple scripts or your BSS/OSS.

                Add paramter '--env /usr/local/etc/exabgp/exabgp.env' to use the default environment values.
                
                For example configuration see the ${PACKAGE}-doc.tcz extension.
